The book brings together the following issues:Theory of deterministic, random and discrete signals reproducible in oscillatory systems of generators;
Generation of periodic signals with a specified spectrum, harmonic distortion factor and random signals with specified probability density function and spectral density;
Synthesis of oscillatory system structures;
Analysis of oscillatory systems with non-linear elements and oscillation amplitude stabilization systems;
It considers the conditions and criteria of steady-state modes in signal generators on active four-pole elements with unidirectional and bidirectional transmission of signals and on two-pole elements; analogues of Barkhausen criteria;
Optimization of oscillatory system structures by harmonic distortion level, minimization of a frequency error and set-up time of the steady state mode;
Theory of construction of random signal generators;
Construction of discrete and digital signal generators;
Practical design of main units of generators;
