Signal analysis in linear time-varying systems

Abstract

Signal analysis and system synthesis are essential tasks in linear time-varying (LTV) systems electrical and control engineers are called upon to perform. This paper emphasizes the analysis of LTV systems in the frequency domain by the aid of the two-dimensional Laplace transform (2DLT)techniques. Specifically, the bifrequency-domain models of basic LTV network elements are determined. Applications of the bifrequency characterization of LTV systems are illustrated in detail to demonstrate the merit of the proposed convenient 2DLT approach.
