Efficient FIR Filtering for Decimation - Binghamton

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… WebJul 6, 2009 · Considering I have to implement this filter on FPGA, this appears to be a very huge number for the taps. A little reading on Polyphase FIR filters indicated me that the total number of taps *per every sub-filter* in a polyphase structure should be ceil(1005/M1) = 50 and so I would have M1=20 such filters.
