ABSTRACT: This Inventor's Certificate introduces a bridge-type square-law function,
~generator with a transformer input. Two adjacent arms of the bridge contain vacuum-
tube triodes operating in the region where Ri is a linearfunction of U while fixed
'resistances are connected in the other two arms. Conversion accuracy A increased
,by making the control circuit of the generator from two transformer windings con-.
,nected in opposite phase. The voltage fromthese windings is fed t6 the control
'grids of the tubes. The control circuit also contains a modulating winding which is
:connected in series with the power supply of the bridge. A compensating winding co-
~phased with the modulating winding is connected in the circuit of the output diagonaL

TEXT: The present paper gives 6 method of determining the transmission
functions of systems expressed by ordinary differential equations of the
n-th order with variable coefficients if these coefficients are polynomials,
The paper (Ref. 1) shows that the transmission function of the dynamic
system investigated here is a particular solution of the following dif-

the transmission function of the system investigated. N(t,p) and M(t,p)
are obtained from the operators N(t,D) and M(t,D) by substituting p for
tile operator D d/dt. t is an independent variable and p is a parameter

Determination of the Transmisoion Functions S/103/60/021/012/001/007
of Some Systems With Variable Parameters BO)2/Bo64
In the region of' the variable p, relations are derived which. determine the
transmission function Y(t,p), and a special case of equation (3), equa-
tion (5), is investigated. In this connection two theorems are confirmed:
Theorem 1): if Y (t,p) is the solution of equation (5), the function,
1
formula (6), is a solution of equation (3). Theorem 2): There is a solu-
tion Y(t,p) of equation (5), which represents the solution of equation (7).
- Such systems are investigated the.equations of which have coefficients
which are polynomials of the first and second degree. Equation (7) for
such systems is solved. - The transmission function of the following
three cases is investigated: In equation (3), the coefficient of N(t,p) is
1) linear with respect to t, 2) it is a polynomial of the second degree,
and 3) a polynomial of the q-th degree, - It is pc`r~f-! -t that in the
general case the uze of both theorems instead of enl,~7~'Lica 'i) i's con-
