Abstract In the self-excited oscillator circuit proposed here the frequency is con-,
trolled by varying the bias voltage. This is accomplished by adding to the
circuit a supplementary tank circuit tuned approximately tc a haromonic of
the fundamental frequency and SAcluded in a positive-feedback loop. It is
indicated that frequency deviations of approximately 5 - 1C% are obtainable
in such systems. This is confirmed by experimental results.

TITLE 7167 ~-Osc=llation Systems with Two Degrees of Freedon and

Issued: 11 / 1956
The problems to be investigated are: 1.) The dependence of the generating fre-
quencies in the synchronous zone on the parameters of the generator, and
2.) the question of the stability of the3e frequencies, The conclusions
arrived at here disclose a number of possibilities for the application of such
generators, Besides, it is possible, on the basis of these conclU31ons,, to
explain phenomena occurring in those systems in which the additional circuits
with divisible frequencies are found to be parasitic.
First, a two-circuit autogeneratoz with backcoupling is investigated for
approximated divided inherent-frequencies, and an analysis is carried out in a
general form on the basis of the slowly modifying complex amplitudes. A
system of four equations is derived in which the right parts of the first three
equations do not depend on the phase, so that investigation is confined to the
analysis of the first three equations. Next, synchronous operation is examined,
on which occasion it was found that the synchronous zone is proportional to
the greater extinction, i.e. to the extinction of the "rough" circuit, The in-
stability of the generating frequencies is caused by two factors: 1.) By the
instability of the inherent frequency, and 2.) by the instability of the feed
voltages., It is shown that with a great difference of extinction the instability

Radiotechnika, 11, fasc.10, 66-76 (1956) CARD 2 / 2 Pk - 1597
of the generating frequencies is near the instability of thin circuit with the
lower extinction, The influence exercised by feed voltage on the generatin`g
frequencie3 is investigated and the stabilizing effect of the circuit with low
extinction becomes apparent,
The instability of the oscillation frequencies is determined by the circuiz
with low extinction, i.e. by its stability and by the extent of extinction,
This stabilizing effect can easily be represented physically. It is thua pos-
sible, if the difference in extinction is great, to divide the autogenerator to
be investigated into two single-circuit autogenerators, of which the one with
the favorable circuit synchronizes the other with the rough circuit.
With analysis in the general form it is not possible to form a clear concep-
tion of the operation of the autogenerator under investigation, but the results
obtained on this occasion make it possible to become acquainted with the
possibilities for the application of such systems, namely, for dividing or
multiplying the quartz frequency (quartz being a favorable circuit) as well as
for the realization of frequenev modulation.

PERIODICAL: Radiotekhnika i Elektranika, 1957, Vol 2, Nr 1, pp 44-56 (USSR)
ABSTRACT: Two coupled oscillators having approximately multiple frequencies are
investigated mathematically. Mutual synchronization of oscillations can take
place in such a two-oscillator system within a certain frequency-difference band.
Determined is how the conditions and frequencies of oscillations and also the
synchronization bandwidth depend on the frequency multiple and the oscillator
parameters. Some peculiarities of beating conditions (out of the synchronization
band) are examined. The problem of synchronization of an oscillator at its fun-
damental and multiple frequencies is usually examined in a simplified way, ne-
glecting the reaction of the oscillator being synchronized on the master oscillator.
Since in real physical systems such a reaction practically always takes place,
an investigation of the mutual synchronization of two oscillators is of interest.
Fundamental -frequency grid voltages are chosen as independent coordinates. A
complete grid voltage includes the fundamental frequency component and the

second oscillator frequency component (formulas I and Z). S. 1. Yevtyanov's
method (reference 2) is used for development of the truncated differential equa-
tions. As a result of a harmonic expansion of the anode current, mean trans-
admittances are found (14). Synchronous conditions are mathematically con-
sidered (formulas 20 through 24), as are frequency -multiplication conditions
(formulas 25 through 29), frequency -division conditions (formulas 30 through
37), and beating conditions (formulas 38 and 39). The synchronization band is
given in formula (37). A two-tuned circuit oscillator (figure 2) was used to
verify experimentally the above theoretical conclusions. -Such an oscillator is
equivalent to a system of two mutually -coupled single-circuit oscillators, pro-
vided they have identical tubes and the coupling between them is selected in
such a way that the fundamental -frequency voltage of each oscillator is fully
applied to the grid circuit of the other oscillator. The experiments have con-
firmed the principal theoretical inferences. Quantitative dependence of maxi-
mum synchronization bands on multiple frequencies under frequency-diviBion
and frequency -multiplication conditions agrees well with the theory. In the out-
of -synchronization zone, simultaneous two-frequency oscillations existed with

on the detuning of the oscillatory circufts and increases with the increase of
detuning. As the detuning grows, in the case of sufficient regeneration of each
circuit, the system passes smootbly from synchronous conditions at a given
multiple into the beating conditions, then into synchronous conditions at another
multiple, etc. , from the multiple 20 through the multiple 2. The remarks of

TITLE: Thermal grid emission in metal-ceramic tubes.
(Termoemissiya setki v metallokeramicheskikh lampakh).
PERIODICAL: "Elektrosvya~" (Telecommunications), 1957, No.4, April,
pp. 12 - 21 (U.S.S.R .)
ABSTRACT: The authors give results of an experimental
investigation of the thermal emission of the grid in
metal-ceramic tubes. Results proved to be in good
agreement with theoretical considerations. The thermal
emission from the grid results in erroneous indications
of measuring instruments in the anode circuit. The
effective power and the efficiency decrease, while
input power from the driving stage is increased, so
that the overall gain of the stage is sharply reduced.
These effects are due to the increase of the d.c.
component of the anode and decrease of the d.c. component
in the grid circuit. The thermal emission produces
substantial distortions when anode modulation is used,
this increase being due to additional pulses of the
anode current which reduce the value of the fundamental.
This distortion is increased by use of the automatic
bias. For the types of tubes which were used in the
experiment, i.e. GI-?B, GI-6B and GS-9B, the thermal
emission occurs witt instantaneous grid voltages e g max)55VI

This '7ould tend to restrict the use of currenf

applications. The experiment was carried out at low
frequencies 16 Kc/s) so that tile transit time could be
disregarded. At UHF the transit time of electrons has
to be taken into account and a supplementary experiment
should be designed. The diagram of the experimental
circuit is given. 2 theoretical 9nd 3 experimental
graphs are drawn, oscillograms of anode and grid current

working of the frequency-amplifiers and the frequency-
transformer according to the scheme with a grounded grid
is examined. As given are assumed: efficiency at a load
Pn, resonance-resistance R axx of the anode-circuit and the
tube-parameters. It is assumed that the anode-voltage E a
and the impulseheight of the anode-current I n are not
limited at the investigation. Later on criterions are
introduced for the valuation of the usefulness of the
recommended working. The anode-reaction is not taken under
consideration here. The given efficiency at a load can be
kept at different values of the amplitude of those harmonic

height In and the cut-of angle of the anode-current 9. In
this place the question of the influence of I n and 0 upoa
the resulting degree of effect of the anode circuit and upon
the coefficient of the cascade amplification according to
the efficiency is examined. It is assumed, that the anode-
voltage E& at any current-value Ian is chosen in such a way
that the critical working of the generator is guaranted. In
order that the received results get a general character and
can be applied for any tubes, the amplitude of the current
Ian is characterized by the quantity of the degree of effect
of the intermediate circuit 71k' It is demonstrated that at
a limited quantity of the resonance-resistance in the circuit
at amplifiers with grounded grids a out-off angle of the
anode-current of 9 - 900 are recommended. k -7eduction c-f
this angle reduces the coefficient of the cat3cade-

efficiency at a load the impulseheight of the anode-current
determines the circuit degree of effect and influences
substantially the energy conditions in the anode-circuit.
In the output cascades it is necessary in order to increase
the general degree of effect of the transmitter to chose
the impulse height of the anode-current according the
minimum-efficiency used by two cascades. It is shown, that
at the projecting of the intermediate cascades the fact
that the same arv loaded by the cathode circuit of the
succeeding cascades (which form a nonlinear resistance) is
to be taken into consideration. In order to multiply the
frequency in the intermediate cascades of the transmitter
the cut-off angle of the anode-current has to be chosen
according to the conditions for the maximum cascade-
amplification according to the efficiency. For the doubling
of the frequency a 0 - 750 and for the tripling of the same

the sum of the resonant frequencies w1 and w2 of the filters
is applied to the mixers from an external oscillator, then
self-oscillations at two difference combination frequencies
W" = Wo - W' and wl = wo - wit arise in the circuit, and
the sum of these difference frequencies equals the frequency of
the external oscillation voltage. By tuning the circuits in
9pposite directions, the Generated frpouencies can be
c:ianged over a range of frequencies. It is shown that, if the
external frequency is stable, then the inGtability of the
generated voltages is determined by the diffprence in the

filter circuits. If the filter circuits are identically
constructed, then the instability of the generpted frequenc;Les
will be very small. Equations are developed from which the
amplitudes and frequencies of the generated voltaGes ray be
computed. The effect of supply voltage changes on the stability
of the generated frequencies is also analysed.

which the theory is developed, but several possible variants
are also discussed (Figures 3 - 8). The filter ci-rcuit voltages

oscillations are then deduced. The relationships between
the instabilities of the individual filter frequencies and
the instability of the generated frequencies is analysed.
The results were checked experimentally, using circuits of
Figures 2 and 3. The external generator frequency was
800 kc/s and the filter frequencies were 420 kc/s and
380 kels. When both capacitors were re-tuned in opposite
directions, a smooth change over approximately 2 kc/s was
obtained (Curve 1 of Figure 9). The instability was checked
by re-tuning both capacitors in the same direction
(Curves 2, 3 and 4). For Curve 2, the absolute changes in
capacity were equal; for Curve 3, the relative changes in
capacity were equal. There are 8 figures and 2 Soviet refs.

TITLE: The Synchronization, Division and Mt-tiplication of a
Frequency With Increased Phase Stability

ABSTRACT: The author recommends using a combined frequency gener-
ator as a synchronizing generator providing an increa-
sed stability of the free oscillation frequency. For
amplifying, dividing and multiplication of a frequency
the synchronization of a self-oscillator to the basic
or multiple frequency is frequently used. In this case,
the self-oscillation frequency is equal to or multiple
of the frequency of the external influence within the
limits of a given range of detuning of the oscillator
circuit (zone of synchronization). Within the synchro-
nization zone, the instability of the self-oscillator
circuit parameters does not have an influence on the
Card 1/3 frequency to be generated, but it leads to a phase in-
0
