Relation between Analysis Filters' Symmetry Polarities and Lengths of M-channel Alias Free Linear Phase Filter Banks

Abstract

M-channel alias-free linear-phase filter banks (AFLPFB) include M linear-phase (LP) FIR analysis filters and have a LP distortion function. Linear-phase perfect-reconstruction filter banks (LPPRFB) are apparently a class of AFLPFB, and widely used in various applications. Although the filters' symmetry polarities and lengths of analysis filters are studied… (More)
