A New Method for Measuring the Performance of Weakly Nonlinear and Noisy Systems
Hans Wilhelm Schüßler, Yanrui Dong · Frequenz · 1990
A method is presented for measuring the performance of real systems, which are at most approximately linear and in addition noisy. Based on a model consisting of a linear subsystem and a nonlinear and noisy one the method permits the characterization of these systems by a complex frequency response and the power density spectrum of the disturbance respectively. The procedure has been implemented using an integrated signal processor under PC-Control
