A new method for the design of two-channel, perfect reconstruction, anal y sis/synthesis QMF bunks is presented. The filters of the banks are HR, power complementary, linear phase, and are represented by means of complex allpass functions. Design procedures based both on numerical approximation and on a flatness constraint imposed on the frequency responses of the filters are given.

Abstract

A new method for the design of two-channel, perfect reconstruction, anal y sis/synthesis QMF bunks is presented. The filters of the banks are HR, power complementary, linear phase, and are represented by means of complex allpass functions. Design procedures based both on numerical approximation and on a flatness constraint imposed on the frequency responses of the filters are given.
