Abstract

Abstract: Results of testing of algorithm for estimation of phase-frequency characteristics of vibration protection systems for existence of significant non-linear distortions are presented. Estimations of maximal error are obtained for phase shift changes from 0.2 to 0.0001 angle degree in dependency on ADS capacity and amount of sampling. The algorithm is realized as m -files of MatLab software.
