ABSTRACT: Several reasons for the inadequacy of the standard
kinetic-equation formalism to non-optical transitions between dis-
crete spectrum states are pointed out. The authors then propose to
describe the processes accompanying multi-phonon nonradiative com-
bination by means of a system of integral quantum-kinetic equations
based on the formalism of the quantum density matrix, a formalism
in which.the quantum-mechanical and statistical calculation stages

are combined. The method used is essentially that of Kubo (J. Phys.
Soc. Japan, v. 12, 570, 1957). A graph representation is obtained C
for the recombination coefficients.with the aid of the technique
of Konstantinov and Perell (ZhETF v. 39, 197, 1960), modified by
Lang and Firsov (ZhETF v. 43, 1843, 1962) to cover multi-phonon
jumps in the case of low polaron mobility. The free relaxation
of the band carriers, which are in quasi-equilibrium with.the
crystal lattice at the initial instant of time, is considered. .A
criterion is considered for the applicability of perturbation the
ory
to the theory of multiphonon-nonradiative transitions. "The authors
thank Yu. A. Firsov and I. G. Lang for valuable information in con-
nection with the covputation procedure, and also A. I. Ansellm
!and Yu. Ye. Perlin for a discussion of the calculation of the re-
combination coefficients*" Orige art. bass S figures and 76 for-.

teorii poluprovodnikov. Izd. "Kartya Moldovenyaske., " Kishinev,,
1964) dealing with
singularitiesof carrier recombination in a quantized electric field.
In the pre- i
sent article, the theory of quantum fluctuations developed by one of
the authors
with Ye. V. Vitin ibid; Izv. AN MR, ser. fiz. No. 12p 111
1964) is
applied to an investigation of the influence of the magnetic field on
the frequency,
,spectrum and the relative magnitude of thenoise connected-with
carrier recombina-
tion and generation processes. 'By introducing an autocorrelation
function for the
quantum fluctuations and enTlaying a diagram technique., the authors
obtain an ex-
pression for the spectral density of the noise intensity# An analysis
of the re-
sults shows that the noise level depends on the magnetic field. It is
Vointed out

ABSTRACT: The density matrix method is used to investigate the
recombination re-
laxation of carriers which-are initiaLly in a state of
quasi-equilibriun with the
crystal lattice. The calculation is based on the Fermi quasi-level
method. The
,recombination mechanism is assumed to be a single-phonon (or
single-phaton). capture!

ABSTRACT: In order to evaluate the serviceableness of valves of
various makes
and designs, as used in Freon machines, a series of comparative tests
have been conducted in the laboratory of the Odessa Refrigeration
Machine Building Plant im.Stalin. The valves were divided in 4 groups:
The ist and 2nd groups comprised various types of the suction and
discharge valves. The 3rd group contained valves manufactured by'the
Austrian firm HSrbiger and the 4th group valves designed by Engineer
A. Shmyglya. Thecharacteristics of the 4 types of valves are shown
in Table 1. The tests were conducted with compressor 2FV-10 at certain
fixed initial and final temperatures, -15 Ob and 300 C. A timing
device
recorded the time necessary for bringing the pressure in the receiver
from 0 to 5 atmospheres. The best time - 22.5 seconds - was made by
group 4 valves. Table 2 shows the results of comparative tests
obtained
by the 4 groups at temperatures indicated. The highest volumetric and
Card 1/2 energy coefficients of the compressor 2FV-10 were obtained
with valves

of group 4 with reduced dead space. The discharge coefficient of the
Freon compressor falls sharply with the increase of dead space
starting
from 3.5% for example. The reduction of dead space in Freon
comDressors
of average output to below 2% holds practically no advantage.

ABSTRACT: This Author's Certificate introduces.a refrigeration unit
which uses a two-
component coolant. The device contains a compressor for the
two-component vapor, a
water- or air-cooled condenser where the high-boLling component is
li~quified, a vapori.
zing condenser for liquefaction of the-low-boLling element by
vaporization of the high-
boiling component, 4 vaporizer for cold production and regenerated
heat exchangers in
which both components are recooled. The overall dimensions are
reduced and the power
indices are improved by using a booster at the input of the
ccmpressor for compressing
the vapor of the low-boLling component.

noted that these changes are: increase in the threshold voltage,
increase in the plateau glope, etc. Such changes are usually
observed after 107 to 10 pulses a~d determine the working life
of a counter. High-voltage self-quenching GM-counters are
usually filled with an inert gas such as argon plus a small
proportion of some organic vapour such as ethyl alcohol, iso-
pentane and others. At the moment of recording of an ionising
particle, dissociation of the organic molecules takes place.
As a result of the irreversible breakdown (in the discharge)
of the organic molecules the working characteristics of the
counter c4ange. ccording to the existing ideas in each dis-
harge 10'; to M 6 organic molecules are broken down. In

counters of normal dimensions there are 10 20 molecules of the
quenching material *Rd therefore all these molecules ought to
dissociate after 10111 counts. However, normal working of the
counter is disturbed much earlier. In the present papew the
authors give results of a mass-spectrometric analysis of the
gas mixture during the working of the counter. The counters
which were used for this experiment were of the usual co-axial
form. The tungsten anode was 0.1 mm. in diameter and had a
working length of 80 mm. The cathode was in the form of a
layer of copper deposited on the inner wall of the glass
envel-
ope. This system is shown in Yig.l. Counters were filled
with 15% (by pressure) chemically pilre CH2(OCH 3)2 and the
pressure was brought up to 100 mm HS by the addition of argon.
Two groups of counters were used. The first group consisted of
60 counters and was used to study changes in the chemical
composition of the filling and the characteristics of the
counter as functions of the number of counts. The second
group,
consisting of 70 counters, was used for both the above
purposes

and the study of changes in the amplitude and the count ate as
functions of the number of recorded counts. Results of these
measurements are summarised in Figs. 2, 3, 4, 5 and 6. Fig.2
shows the change in the characteristics of counters as a
function of the number of recorded counts. It can be seen that
the threshold voltage increases by 50 to 60 volts, the length
of plateau decreases by about 260 V and the plateau slope
increases from 2 - 3 to 18 - 20% after 2 x 100 counts. Mass
spectrometric analysis has led to the conclusion that the amount
of dissociating organic molecules is proportional to the number
of recorded counts. In the gas mixture of the counter, sub-
stances with mass numbers 16 and 28 appear, and these worsen
t!.Le counter characteristics. There are reasons to suppose that
Ghe mass number 16 corresponds to oxygen which has a strong
influence on counter characteristics. The ageing of the counter
is connected not only with the dissociation of the organic
component but also with changes in the surface of the cathode.
The present experiments have shown that, with the right exploit-
ation of argon-CH2(OCHI,)2 filled counters, they can be used for
Card3/4 recording up to (1 to 2") x 108 counts.

ABSTRACT: Three groups of counters were investigated;
Group I. In this group the counters had nickel cathodes,
10 mm ii! diameter, kovar anodes 0.5 mm in diameter, the work-
ing length of the anode beingogO mm. They were outgassed
and subsequently heated to 25 in chlorine. In order to
remove volatile products, additional heating at 140-1500C
was carried out before the final filling at a pressure not
-4
exceeding 10 mm Eg. The counters were filled with a mix-
ture of Ne, Ar (0.1%) and Br2 (0.03%) at a total pressure
of 600-650 mm Hg.
Group II. Counters of identical construction. The addit-
ional heating to 1500C not carried out.
Group III, Counters of Type STS-1 with the geometrical di-
mensions as the above but having stainless steel cathodes.
Figs 1-3 show the results obtained. Fig 1 shows the depen-

dependence of counter characteristics on temperature of the
surrounding medium. Ciiiwe 1 shows the dependence of the be-
ginning of the plateau on temperature for a STS-1 counter
and a Group I counter, and Curve 2 shows the dependence of
the end of the plateau on temperature for a similar pair of
counters. Curve 3 shows the dependence of the efficiency
of Group I counters on the temperature of the surrounding
medium. It is concluded that changes in the characteristics
of halogen counters as the temperature increases are due to
the evaporation into the working volume of the products of
interaction cC the halogen with the material of which the
counter is made and desorption of excess chlorine. Prelim-
inary removal of these products by heating,extends the thermal

ABSTRACT: A description is given of a number of corona
counters
designed on the basis of the work reported in Refs 3 and
4. The SAT-7 a - particle counter is shown in Fig 3.
It consists of a glass envelope with a ferrochrome ring.
A 10-*ll It thick mica plate is attached to this ring and
forms the end-window of the counter, The ring serves as
the output contact for the metallic cathode which is
evaporated onto the glass and the mica. The anode is
in the form of a hemisphere 1 mm. in diameter (in Fig 3,
1 is the glass envelope, 3 is the anode, 4 is the
cathode, 5 is the ferrochrome ring, and 6 is the mica
window), The SAT-8 counter is designed to measure the

particles, Its

cathode is in the form of a metallic cap made from
ferrochrome which carries a mica window 3 4 IL thick
and 4 mm in diameter. The anode is similar to that
in the SAT-?. The slow neutron counter SNM-9 has the
usual cylindrical geometry, Its cathode has a diameter
of 18 mm. and is made of stainless steel. The element
sensitive to slow neutrons is a layer of amorphous
boron deposited on the inner surface of the cathode,
The thickness of this layer is grj8ter than the ranGe
of the products of the reaction B (na) Li?. All the
three counters are filled with a mixture of neon with
a small admixture of argon (not greater than 2%). The
corona noise usually does not exceed 5 mV in SAT-?
15 MV in SNM-9 and 25 mV in SAT-8 counters and can be
easily cut off with a suitable discriminator,, The
maximum amplitude of the working pulses is 100 -' 300 mV
which corresponds to a gas amplification coefficient of

the case of the SAT-7 cou4ter. Best results are obtained
with a load of 5 x 1OF34 -~'-109 ohm. With such load
resistances,'the voltage ranges are 450-.'1000 and 700
2500 volts for the SAT-8 and the SNM-9 counters
respectively. The plateau slope is practically zero.
In the case of the SAT-7 counter a 1 Meg resistance is
sufficient and the length of the plateau is 300 -*

ABSTRACT: The dose characteristics of the low-voltage
halogen
counters STS-1, STS-2, STS-5, STS-6, STS-8, SGS-5,
SGS-69 SBT-10 and SGS-7 have been measured and are now
reported. The parameters of the first six counters
were given by Dmitriyev (Ref 2. a review paper), The
SGS-6 counter is similar to the SGS-5 but its cathode
has a longer working length. The SBT-10 s designed
to detect soft P-radiation and has a 30 cJ mica window,
It consists of ten sections placed in a common envelope.
The cathode of each section is in the form of a half-
cylinder, 5 mm in radius. The anode of each section
is 55 mm long and has a separate output terminal. In
the SGS-7 counter the cathode and the anode are in the
form of discs 10 mm and 0.5 mm in diameter, respectively,

parameters (threshold, length-and slope of the plateau)
of SBT-10,, SGS-6 and SGS-7 are analogous to the parameters
of all the low voltage halogen counters described in Ref 2.
Table 1 gives the main parameters of the counters. The
first colilmn gives the type of the counter, the second
column the cathode diameter in mm and the third colimn
the working length of the anode in mm. The counting
rate was measured using the PS-10000 meter, the input
sensitivity being 0.1 V and the resolvingotime 1 11sec.
The irradiation was carried out using Go sources whose
activity was 0,01-5 Ra g equiv, The dose was determined
to within + 10~6~ In the experiments the SBT-10 counter
was connecTed as shown in Fig 1. while all the remaining
counters were connected as shown in Fig 2. The dose
characterist cs and the plateau slope were determined
using R = 1A Ohm, Figs 3 and 4 show the dose character-
istics of the'above counters measured at the working
voltage. It is clear that in the majority of the counters
there is a maximum counting rate on the dose characteristic,

pulse height at-large counting rate. Under these
conditions the potential difference across the counter
is not fully established. Since halogen counters give
pulses with unequal amplitudes (Ref 3) it follovis that
some of the pulses may fall below the threshold of the
detecting device. Table 2 gives the dose characteristics
of the counters, where column 1 gives the type of the
counter, column 2 the dose range in lir/sec, column 3
gives the counting rate at the appropriate dose in
pulses/sec and column 4 the maximum counting rate in
pulses/see. Table 3 gives the dependence of the plateau
slope on the dose, in which the first column gives the
dose in jLr/sec and the second and third columns give
the plateau slope in percent/Volt for the STS-5 and SGS-5
counters, respectively (the headings of columns 4, 5 and
6 are the same as those of 1, 2 and 3). Table 4 gives
the resolvIng time of the counters. Column 1 of this
table gives the type of the counter, columns 2 and 3 the
resolving time in jisec at 100 pulses/sec and at maximum
counting rate, respectively (columns 4, 5 and 6 have the

great effect on the dose characteristics (Figs 5 and 6
in which the curves are plotted in ascending values of
the load resistance). In the detection of large doses,
the anode voltage must be well stabilized because in
this case the plateau slope is considerably increased.
It is noted that the plateau slope and the character of
bits change with increasing counting rate differs from
counter to counter since it largely depends on the
technology of manufacture and the conditions under which
the counter is used. However, it follows from Table 3
that the plateau slope increases with increasing dose
(i.e. increasing counting rate).

TITLE: A Gas Discharge Gamma-Ray Detector With a
Logarithmic Sensitivity
PERIODICAL: Pribory i tekhnika eksperimenta, 1961, No*l, PP-51-52
TEXT: The detector (counter) is in the form of a two-
electrode gas discharge system with a strongly nonuniform electric
field. The counter can be filled with any of the non-self-
quenching gases normally used in Geiger counters. P1g.1 shows
the arrange~nent for the recording of y-rays by the corona
counter.
A voltmeter which measures the potential difference between the
electrodes is connected in parallel with the counter. In the
simplest case, an electrostatic voltmeter can be employed. if
the applied voltage exceeds the voltage necessary to initiate the
corona discharge, and the load resistance R is greater than or
equal to 109 ohm, then in the absence of ionizing radiation the
voltmeter will indicate a constant voltage Vs. The introduction
of a y-radiation leads to an increase in the current through the
counter, and consequently the voltage indicated by the voltmeter

changes by, say, &V. LW depends logarithmically on the
intensity of the y-radiation, and its magnitude reaches 100
volts
or more when the intensity changes by an order of magnitude.
Qualitatively, the operation of the counter can be described as
follows. When the applied voltage is less than VS, the counter
operates as a proportional counter. Under these conditions the
volt-ampere characteristics are as shown schematically in Fig-3.
In the absence of y-radiation the volt-ampere characteristic has
the form of a rapidly rising curve which for V > Vs goes over
into the usual characteristic of a corona discharge, which is
not
very dependent on the y-ray intensity. The dotted lines in Fig-3
show the dynamic characteristics of the counter for various
applied voltages and loads OMI > R2). The introduction of
radiation leads to the displacemat of the working point from A
to B (or from A, to Bt, etc.) and the current passing through
the circuit changes from ii to some value i which is determined
by the y-ray intensity. At the saine time, the anode potential
decreases by 6V = V - Vs. The new position of the working

point (HO) corresponds to the proportional region. Two factors
influence the change in the current, namely, an increase in the
y-ray intensity gives rise to an increase in the cut-rent, but
on
the other hand this increase in the current in the proportional
region reduces the gas amplification coefficient (Tolchenov,
Ref.2). As a result, the dependence of &V on the y-ray
intensity is logarithmic. As can be seen from Fig-3, the higher
the supply voltage the lower the load resistance R and the
higher the upper working limit of the instrument. Fig.2 shows
the change in the anode voltage &V as a function of the y-ray
intensity (r/hr) for different values of R (ohms) as shown.
These results were obtained with a cylindrical counter, 26 mm
i=
diameter and 130 mm long, filled with a mixture consisting of
Ne + 2% Ar at 500 mm Hg. The value of Vs was 700 volts and the
applied voltage was 750 volts. The lower working limit under
these conditions was about 0.1 r/hr. Fig.4 shows the change in
the anode voltages &V as a function of the y-vay intensity
(r/hr) for a counter 26 mm in diameter and filled with helium,

ABSTRACT: A proportional counterdesigned for detection of 1-10-kev

described. To meet the requirement of a large-area input aperture of
minimum thick-..,
ness, the design contains acathode equipped Iwith two 10-p Al film
apertures 25 x 16 m
each. To reduce attenuation of fluorescent radiation by the
surrounding air, the
counter itself is placed in a vacuum while the remainder of the unit
is sxxbjected to'
normal atmospheric pressure. Provisions are made,for connecting the
output of the
counter to a scintillation counter.. The active elements of the
counter are a stain-*
less steel cylindrical cathode 25 mm in diameter, a tungsten wire
anode 0.05 i3~m in
diameter, and a gas mixture of 90% Ar and 10% CH4 which is passed
through the counter
'interior at a rate of 5-20 cm3/min. Fig. 1 shows the output pulse

Title : Rolbe Rejection o a Filter Auto-Correlation Receiver for
Pulse Signals
Orig Pub : Radietelchnika, 1956, 11, No 4, 20-30
Abstract The signal-to-noise ratio is determined at the output
of a simple cor-
ri,6ation receiver, which has aq averaging element consisting of
a low-
pass filter. By signal-to-noi~e'ratio is meant the ratio A of
the square
of the maximum increment in the de component at the output of
the receiver
in the presence of a useful signal to the average square of the
fluctuations
at the output in the absence of a useful signal. Assuming that
the fluctu-
ation noise has a uniform spectral density, and assuming the
input (band)'
filter of the receiver and the averaging element to be ideal
filters, the
author derives an expression for the dispersion of
theLlIuctuations and for
the maximum value of the increment of the dc component at the
output of the
system under investigation. These values make it possible to
determine A.
It turns out that the opti;mum value of the time delay'r at
which A = Amax,
depends on the bandwidth -of the input filter. If the
input-filter has an
optimum bandwidth, the above system has no advantages over a
receiving set
with a square-law detector. Increasing the Vandwidth of the

ABSTRACT: It is shown that, with the aid of a'samewbat
complicated construction
of the correlation reception system, it in possible to
eliminate the
usual faults and to increase the J-1nity from disturbance of
the
system. (Usual faults: if time of delay in greater than the
optimum
time, the immunity from disturbance of autooorrelation
reception
decreases to zero if the time or delay boomen equal to the
duration
or the useful aIignal).'This in attained by switching an a
synchronous
key-devioe into one of the channels of the system. The range of
application in, however, limited by the class of the
synchronous
pulse system. kt first it in shown merely by approximation
that the
dispersion of the noise integral is diminished in the case of
re-
generative reception* and that therefore the 4-unity from

anoe increases in the moo of the method suggested. This is
proved
with accuracy in the course of the second part of the paper.

ABSTRACT: The article presents one of the possible variants of a

reception system , an integral self -correlation system with

ing of the impulse signal and black-our. ox tne Iluctuating dis-
turbance. Following the principal scheme of the elementary self-
correlating reception system (Fig.1), the last apparatus has to
register the short-time self-correlation factor miscellany of the
signal and the disturbance y (t). The~presence of a synchroniza-
tion channel allows the realization of the coincidence of the
neutralization interval T with the interval of active transmis-
sion. The advantage of the signal disturbance relation at the '

advan-
tage appears as a conserquence of weakening the disturbances
at the
installation output, combined with a barely'existing
reduction of
the useful signal. The disadvantage of the system is, that in

of absent synchronism between the intervals of useful

and the intervals ofineutralization, not all the advantages

ABSTRACT:
The purpose of the article is to determine the cor-
relation
between the intensity of a treshold signal
of random nature, acting on
the input of a radio-
meter with a square-law detector, and the
probabili-
ty of detecting this signal at the output of a re-
gistering
instrument during a given time of analysis,
and with a known intensity
of noise in the radio-
meter channel. The probability of correctly
deter-
mining the fact of the absence or presence of,the
desired signal
is a function of signal intensity,
noise intensity, and the time of
analysis. Deter-

purpose of the article. A block diagram of the
radiometer circuit (Figure 1), consisting of in-
put filter, detector, averaging device, and re-
gistering instrument, is very briefly discussed
by the author. Readings of the registering instru-
ment are proportional to the output voltage of the
averager, and as both signal and noise are of a
random nature, these readings will also have a
random nature over a finite time of analysis.
Readings will fluctuate about a certain average
value, equivalent to the value of the average power
of the mixture of desired signal and noise. Pres-
ence or absence of the desired signal can be de-
termined from the magnitude of a particular value
of reading; a reading higher than a certain con-
trol value corresponds to the presence of the Sig-
nal, and vice versa. Taking the probabilities of

expressions for the minimum detectable ratio of
signal to noise for a radiometer with the averag-

as small a signal as desired may be detected pro-

a given signal/noise ratio, an increase in the
probability of detecting the desired signal de-
mands a corresponding increase in the duration of
the analysis; improvement of the signal/noise

with the corresponding ratio at the input is greater;

The ergodic theorem shows that M(L-) and FCO are
equivalent. In the case when f I(t) = f2(t) , Eq. (1)
represents the so-called autocorrelation function F 11 (-"') .
It is known from the Wiener-Khinchin (Ref. 3 - A.M. Yaglom,

where PW is the energy spectrum of the function. The
equipment employed in the evaluation of correlation functions
can be divided into three groups, depending on the underlying
principle of their operation.,
A) the devices based on the principle of the two-dimensional.

probability density;
b) the devices employing the principle of the spectral
function, and
c) instruments based on the multiplication principle.
As regards the devices of the first group, their basic element
is a system for determining the two-dimensional probability
density W2(fIf2t in each point of the three-dimensional
space fl, f2, -c, This usually consists of a device
determining the conditional probability density of the signal
f1 (or f.) for a fixed 'r- and an instrument determining
the unidimensional probability density of the signal f.
(or f2). In this type of equipment the signal fIand
signal f2 . delayed by an amount ^t~, , are applied to the
device which determines the conditional probability den.9ity
W(f 1/f2) which, together with a multiplier M, I integrator I

a generator of linearly changing voltage LG, forms a system
evaluating the conditional average value of f I in the
interval of f, , which comprises the region of the most
probable values of the process and its vicinity. A second
channel of this type of correlator consists of a device
determining the probability density of the quantity f2w(f 2)
a multiplier M2 and another generator of linearly changing
voltage LG, . The signal at the output of the second
channel is proportional to the quantity f 2 W(f2) . The
voltage of LG2 changes within the same limits as the voltage
of LG, but the rate of its change is much slower, so that the
voltage of LG, can be regarded as constant during one period
of LGIL a The generators LGl, LGV. and integrators I, and I.

are synchronized by a signal provided from a synchronising
circuit. The output signals of the two channels are
multiplied by a multiplier M3 and are integrated with respect
to f2 in order to determine the average value of fl(t)f2 (t 4

If the delay time C. is varied, the signal at the output of
the device'represents, therefore, the cross correlation
function for f. and f2 . The principle of a corvelator
can be based on Eq. (2). In this case, the equipment consists
of an automatic spectrum analyser which produces the amplitude
spectrum of the input signal; this is followed by a squaring

circuit where the power spectrum is obtained; the amplitude
spectrum of the latter is then produced by another automatic
spectrum analyzer which is equivalent to the autocorrelation
function of the investigated process. The correlators based
on the multiplication principle can be of two types: those
operating sequentially and those performing instantaneous
analysis. In the second case, it is necessary to employ a
set of fixed delay elements for N&T, with a monotonically
increasing delay. As regards the correlators of the first
type, these simply consist of a delay circuit, a multiplier
and an integrator (with an indication circuit). This
correlator is much simpler than that based on the instantaneous
analysis principle. However, the sequential-analysis correlator
has the disadvantitge that the time taken by it for determining
the value of the correlation function is n times longer
than that of the more complex correlator. Multiplier
correlators can also be designed differently. Thus, for
example, the correlator can be constructed as follows. The
investigated signal f and a portion of the signal f

by means of a calibrated sy=.netrical potentiometer and a phase-
inverter circuit. The difference produced at the outputaCA. is:
A(t) = f1W -.ar 2(t)
and this is applied to a squaring circuit, an integrator
and, finally, the indicating device. it can be shoi-m that the
minimum of the mean square value of
2
A (t) corresponds to the case when the multiplier a is
equal to the correlation coefficient 11,,, Consequently,
the measurement of the correlation coefficient is equivalent
to the setting of the above instrument in such a way that its
indicator gives a minimum; the 6oefficient a is then read
on the calibrated scale of the potenxiometer. The above
multiplier correlators are not suitable for the measurements
of the autocorrelation functions of slowly changing processes*

In this casev it is possible to base the correlator on the
following formula:

The resulting correlator consists of N channelsi the
investigated signal fIis applied to the input of these
channels and their outputs produce expansion coefficients

of JL9 n
filter having a suitable impulse response hn(t) , a
multiplier N nand an integrator In . The correlator also
comprises another set of filters having impulse response hof

Consequently, periodic signals corresponding to hol his
h2v ... are formed at the output of each filter. Another
set of multipliers M2 perform the multiplication of the
n
expansion coefficients a n and impulse responses hn . The
products of the multipliers are then added in a summation
circuit. The resulting signal is equivalent to the auto-
correlation function of fjL . The determination of a
correlation function can also be performed by digital devices.
In this case, each point of the correlation function is
evaluated by averaging a sufficiently large number of the pairs
of products of the values of the investigated process f(t);
