Two-channel IIR/FIR filter banks with very low-complexity analysis or synthesis filters: finite wordlength effects

摘要

A new class of two-channel IIR/FIR filter banks was introduced by the authors in 2000 with half-band IIR analysis filters and FIR synthesis filters. This type of filter bank features very low-complexity analysis filters and simultaneously a low overall complexity. In this paper, we consider finite-wordlength effects of these filter banks.
