In this paper, uniform, critically decimated filter banks are used to approximate nonuniform filter banks wherein different filters have approximately the same magnitude response, but different phase, thus forming a linear periodically time-varying filter whose characteristics are similar to those of a nonuniform bank. This is done by post-processing a number of selected subbands of a uniform bank using a special synthesis filter bank, which combines the selected bands into one. Design methods for the post-processing stage are discussed and design examples are presented
