Polyphase quadrature filter: Music & Measurement

A polyphase quadrature filter, or PQF, is a filter bank which splits an input signal into a given number N (mostly a power of 2) of equally distant sub-bands. A factor of N subsamples these sub-bands, so they are critically sampled. An important application of the polyphase filters (of FIR type) concerns the filtering and decimation of large band (and so…
