Stability Analysis of Modified Coupled-Form Digital Filter Using a Constructive Algorithm
변형된 선합성수 디지털 필터의 안정도 해석
Abstract
Using the constructive algorithm proposed by Brayton and Tong, we analyze the stability of a modified coupled-form digital filter with quantization and overflow nonlinearities, and find the regions in the parameter plane where the filter is globally asymptotically stable. In these regions, the absence of zero-input limit cycles is ensured. This constructive algorithm gives less conservative stability results than the application of Jury-Lee stability criterion does.
