Barkhausen criterion for pulse oscillators

Abstract

This work presents the study of the conditions for forming periodic oscillations of non-sinusoidal pulse waveforms in oscillatory systems consisting of a linear frequency-dependent circuit and an active nonlinear element. Based on Barkhausen stability criterion, an application under the frequencies of all harmonics of output oscillations is discussed.
