Abstract Based on overlapping individual filter character, IIR general parameter filters are used as units of filterbank, whose amplitude and delay characters are all considered. In designing, let filter frequency character in passband region meet the demand, then optimizing the integrated frequency character in transition region with some anti-aliasing or anti-crosstalk measures used, the resulting filter bank can be nearly perfect reconstruction in certain precision. This is a new theory and method of design for filter banks.
