PURPOSE: This monograph is addressed to those desiring detailed and
up-to-date information on the theory and practical design of low-
frequency transformers.
COVERAGE: Though the Soviet radio and electrical equipment industry
has been successful in producing new kinds of,magnetic materials
and magnet wire required in the manufacture of the latest low-
frequency transformers, there has been no data or information in the
literature giving the characteristics of these materials. The book
presents the results of studies made of such characteristics, i.e.,
initial permeability with and without magnetization, curves of

-optimum nonmagnetic gaps for transformer steels and pei-malloys,
curves of harmonic facto:,,s, and Q-factor curves for various magnetic
materials. The mass production and the ever-growing use of electron-
ic equipment require tha't in the design of transformers the struc-
tural and economic requi:?ements of the equipment for which such
transformers are used be taken into consideration. With this end in
view, a discussion of transformers of the least weight and cost,
and an analysis of optimum dimensional relationships of transform-
ers have been included In the present work. The author thanks
Professors V.V.Furduyev and G.A.Levin for their valuable suggestions.
There are 30 references, of which 26 are Soviet, and 4 English.

Title t Rad_io:~ r with semi-conductive triodes
Periodical I Radio 51 42 - 44, My 1955
Abstract I The characteristics of a new economical radio receiver, which uses semi-
conductive triodes instead of the conventional electron tube, are descri-
bed. The receiver is capable of loudspeaking reception of local radio
station trm,.smission and requires only 0.03 - 0.05 W as a source of power.
The sensitivity of the receiver can be incree--ed by adding one FF ampli-
fication stage. It is stated that a well tuned receiver with t,.,-o U, am-
plification stages assembled on semi-conductive triodes and with two IY
amplification stages assembled on flat triodes plus a small frame or mag-
netic antenna built-in in the receiver offers excel-lent reception of
local radio stations. Diagrams; drawings.

Title Selection of Conditions, Calculation of load, and Determination
of nonlinear distortions in amplification stages using junction
transistors
Periodical Radiotekhnika, 10, 28-36, Aug 1955
Abstract The author presents a procedure for selecting operating condi-
tions and basic formulas for calculating low-frequency amplifi-
cation stages using transistor triodes which he states are ac-
curate enough for practical purposes and do not require the use
of the complex and cumbersome equations of four-terminal network
theory. He further states that in the majority of cases the
generally accepted proposition that the load must be matched to
the transistor's output impedance does not hold true.

TITLE: Design of some systems stabilizing the operating point in transis-
torized stages
PERIODICALt Elektroavyaz', no. It, 1962,"^11 - 2.0
TEXT: This arti~.!e deals with the theoretical calculation of the simplest
systems stabilizing the transistqr-stage operating point. No simplifying assump-
tions are made. Three systems using feedback.are examined and the essential for-
mulae are deduced. The authors recall first the general conditions that must be
satisfied as regards.the admissible variation of the transistor-stage output-eir-
cuit quiescent current (minimum and maximum admissible values of this current)ard
speak of the usual methods of calculation. [Abstracter's notet This general part
of the article covers 4 pages.] They examine next the three following systems;
1) Collector etabilization with parallel negative feedbadk (Fig. 3). The authors
briefly enumerate the cases in which this stabilizing system cannot be used. Thoy
show next, on a numerical example, that the use of this system is often quite Pon-
,sible at small values of the maximum initial collector current (Icol in max).

They deduce, for this case, formulae giving. respectively, Rl, Icol max and
Ucol em min, and apply these formulae to their practical example. 2) Emitter
stabilization with series negative current-feedback (Fig. 5). The authors deduce
forrmalae giving R1, Icol max and Iem max, respectively. They mention the advELn-
tages and defects of the emitter stabilization. They apply then their formulae
to a practical example and calculate Rem, Ic'ol In min(minimum initial collector
current for zero colloctor-base voltage), Ub em max, Rl- Icol In max, Ub em min
and Ucol em min. 3) Combined stabilization, where the output stage contains a
decoupling filter Cf, Rk (Fig. 6). The authors deduce here four formulae giving,
respectively, R1, Icol max, Ism max and Ucol em min- Experiments showed that all
the above-mentioned formulae yield results in close agreement with the experimen-
tal ones,the discrepancies, not exceeding a few percent. There are 6 figures.

TITLE. Some problems concerning transistorized audio-frequency class B
stages using power-supply rectifiers
PERIODICAL; Elektrosvyaz', no. 3, 1960, 26 - 33
TFIXT. After enumerating the various causes of non-linear distortions in
transistorized audio-frequency class B stages using power-supply rectifiers (and
namely the distortion due to the power-source impedance Zsource when this imped-
ance is commensurable with the amplifier load Re), the authors discuss the ade-
quate choice of the parameters of the smoothing filter ensuring an undistorted
operation of the amplifier. Sound signals with time-varying level can be consid-
ered as a certain carrier modulated by a relatively slow varying function [Ref.
2: Yu.S. Bykov, Teoriya razborchivosti rechi i povysheniye effektivnosti radiote-
lefonnoy svyazi (Theory of speech intelligibility and incr6ase of radio-telephone
communication efficiency), Gosenergoizdat, 1959]. For simplicity, the authors
assume that the level of the input signal at sound frequency 6) varies c;:)_~inuEol-
dally with the modul-ating frequency a , i.e.:

where m is the sound-frequency modulation factor. Taking into account the cutoff
in. class B amplifiers, the colleot-:~r currents of the triodes canbe expressed as:

k2 W = Ik mod (I + m c I 5r 2 7C 4 ne - 1
where Ik mod = Kinp mod' and k = constant is the current amplification factor.
Expressions in brackets represent a development into Fourier series of half-sinu-
soidal pulses of frequency w , where pulses Ik2 W lag by X behind pulses 'ki(t).
The equivalent circuit of the investigated transistorized stage is given. The
collector voltage is the sum of the voltage of half the primary winding of the
output transformer uT (t) (which does not contain components at the envelope fre-
quency), and of the voltage drop across the power-source impedance due to current
if N (which contains the modulating frequency jQ). Since S2 4 2n 0, and the
filter resonant frequency .9 res 4 2nGj, the voltage drop across Zsource corres-
ponding to components at frequency 2n Gj can be neglected. On the other hand, tak-
