Characterization of Discrete-Time Linear Periodically Time-Varying Systems

摘要

Techniques for empirically characterizing linear time-invariant systems are wellestablished in the technical literature. Classic techniques rely on both the linearity of the underlying system and on the time invariance of the system parameters. Methods for analytically characterizing linear time-varying systems are also well-established in the literature. Typically, these methods rely on the time-varying impulse response or on the system response function. The focus of these methods is on the analytical evaluation of systems with known parameters, not on the empirical characterization of systems. The following paper presents techniques for empirically characterizing discrete-time linear time-varying systems whose system parameters may be only partially specified.
