ANALYSIS OF PHASE AND FREQUENCY CHARACTERISTIC OF FIRST ORDER COMPONENT FOR THE TASK OF FILTERING AND CONTROL OF SPECIALIZED COMPUTER SYSTEM

Abstract

The analysis of phase-frequency response of the first order components on an example of Butterworth and Chebyshev digital filters is carried out in the article, changes of these characteristics at variations of filter transfer function coefficients are shown. Dependences of a phase on level of pulsations are received at the set cut-off frequency for the first order low-pass and high-pass Chebyshev filter
