Abstract
This thesis is interested mainly in the nonlinear analysis
of transistor oscillators. This makes it possible to study frequency
stability of the oscillator and hance try to improve the
stability.
For the duality and similarity between tubes and transistor,
studies have been made for tht previous work in vacuum tubes
oscillators.
The thesis Consist of three chapters.
The first one, gives a survey of the previous work in sol-
ving the nonlinear differential equations in vacuum tube oscillators
and the methods which are used to improve the frequency
deviation from that of the resonator. A new method have been
suggested which was proved theoritically and experimentally to
improve this frequency deviation.
The second chapter, gives a survey of the previous work
on the nonlinear analysis of transistor and the large signal models
which are used. A new method of analysis of that type of
oscillators have been suggested. Also studies on the frequency
and the factors affecting it and methods of improvement are
discussed.
The third chapter, gives, a new general method of analysis
of the oscillator with any active device (tubes or transistors),
also for any oscillator circuit cenfiguration under any class of
operation. The results of that method wa~; checked. by comparing
it with the known results of some :;,pecialcases.
