The problem of analyzing the frequency characteristics of filters in unfinished transient processes (dynamic frequency characteristics) is considered. Such problems are typical both for IIR-filters including the ones based on auto regression models and for FIR-filters, viz. moving average filters. The application of a given approach is especially important for concatenated filters. The methods to reduce the length of transient processes improving dynamic frequency characteristics of filters are analyzed. The aim of the work is to analyze the degree of static and dynamic frequency filter characteristics correspondence depending on the length of the sample and techniques to accelerate transient processes in IIR filters.
Key words: dynamic frequency characteristics of filters, transient process length reduction.
