摘要

作者于2000年提出了一类新的双通道IIR/FIR滤波器组，其中包括半带IIR分析滤波器和FIR合成滤波器。这种类型的滤波器组具有非常低复杂度的分析滤波器，同时具有较低的总体复杂度。在本文中，我们考虑了这些滤波器组的有限字长效应。

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

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.
