A typical convolutional filter has constant coefficients, while a polyphase filter adjusts coefficients depending on the relative phases of the input and output, so the implementations are very different. A polyphase filter bank is a particular architecture for implementing one type of polyphase filter.

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 equidistant sub-bands. These sub-bands are subsampled by a factor of N, 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 high sample rate) input signals, e.g. coming from a high rate ADC, which can not be directly processed by an FPGA or in some ca… WebMar 16, 2024 · For the band limiting, a FIR filter is typically used.
