Abstract
A new method for the design of two-channel, perfect reconstruction, an alysis/synthesis QMF banks is presented, The filters of the banks are IIR, power complementary, linear phase, and are represented by means o f complex allpass functions, Design procedures based both on numerical approximation and on a flatness constraint imposed on the frequency r esponses of the filters are given.
