摘要：

In this paper, a new method for designing perfect reconstruction (PR) two-channel causal stable IIR filter banks is introduced. It is based on a structure previously proposed by Phoong et al. [2], By using a combination of allpass and linear-phase FIR functions, the bumping problem found in the conventional structural PR filter bank is significantly suppressed. The design problem is formulated as a polynomial approximation problem and is sol,ed effectively using the Remez exchange algorithm, Filter banks with flexible stopband attenuation and system delay can readily be obtained using the proposed algorithm.
