Polyphase Quadrature filter - Wikipedia, The Free Encyclopedia
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) Note that it is also possible to build PQF filters using recursive IIR filters. Computation. There are different formulas possible. ... Read Article
