With reference to the paper by Georg and Urkovich (PIRE Nr C

1953)
it is said that an error was committed there which renders

the
resultobtained useless. The error consists in the fact that,

when
introducing the notion of aspeoific spectral density of noi-

se in
the case of a load with a resistance of 1 ohmg the authors

disregs.3~ded the fact that the component caused by the Schottky

effect of the tube depends on the conductivity of the circuitg

whereas the component of thermal noise is independent of it.- In

the
present work the question of the noise coefficient for super-

regenerative receivers is investigated for linear operation, and

the
following conclusions are drowns 1) The noise coefficient F

is
independent of the equivalent frequency domain. Therefore it is

no
use deteraining it unless one is interested in the absolute va-

lues
of the noise at the output of the superregenerator.

2) The
dependence of the coefficient F gn frequency is determined

only by
the character of the input resistance Rin. With an increa-

se of
frequency, Rin decreases and F rises. From the table shown

here it
may be seen that F of the superregenerator exceeds the co-

efficient
F of the superheterodyne only very little. In order to

conclusions given here apply also in the case in which he sup-
erregenerator is used as an intermediate frequency amplifier in a
superheterodyne receiving set.

ABSTRACT: It is assumed that a system consisting of a magnetron, a
tuned circuit having parameters L.C.,r and an external electro-
motive force B having a frequency wl can be described by
Eq.(l) where u is the voltage at the resonance circuit, 1 1
and 1 2 are Turre xitb of the first and the second anode, and
Wo = i/Iff is the resonance frequency of the circuit (Refs-1
and 2). A-feasible solution of the equation is in the form
of Eq.(2) fh~which dl is the negative damping coefficient,
Ltive damping, do is the damping coefficient
d2 is the po$
of the resonance circuit, 61 is the overall damping.
Investigation of Eq.(2) for actual magnetron systems shows that

hundred which is lower than that of a triode operating as a
superregenerator. Experimentally, the superregenerative
regime was investigated on the circuit shown in Fig.l. The
system had a magnetic field of 1 300 and operated at a fre-
quency of 300 kc/s. A similar investigation was carried out
on a double-magnetron system (Fig.4) operating at 3 000 Mc/s.
It was found that the system of Pig.1 gave gains ranging from
10 - 100, while that of Fig.4 had considerably lower gains.
There are 4 figures and 3 Slavic references.

ABSTRACT: In this article the possibilities of receiving pulsed
signals by storage methods in one single- and double-
tuned receivers are discussed. This is in particular
an approach to the noise stability conditions at limited
mean pulse time. It is shown that atgreat mean pulse
times the method of double-tuned storage, as compared
to single-tuned reception provides a certain gain in
noise stability. A model was constructed for experime;~t'j~l
investigations, the block-scheme of which is given. -
The results of the.comprehonsive information collected
are to the point that a double-tuned reception offers
a certain degree of improvement as compared to ordinary
