Abstract

Abstract

The theory of uniform filter banks using all-pass filters is further developed. A filter-bank structure using two-stage all-pass filters is proposed. The pre-stage is half-band filters with period, the post-stage is two pass-band filter banks. The stopband of the pre-ttage filter just controls the don t-care band of the poststage filter using all-pass polyphase, so that a realization of continuous stopband property is obtained Moreover, a method of implementing synthesis filter banks is given, which eliminates aliasing and amplitude distortions of analysis/synthesis system. Finally, an example is listed.
