A class of two-channel IIR/FIR filter banks
Per Löwenborg, Håkan Johansson, Lars Wanhammar · European Signal Processing Conference · 2000
A class of digital filter banks is introduced, in which the analysis filters are half band IIR filters and the synthesis filters are FIR filters. The proposed filter bank satisfy approximately perfect reconstruction and has an exact linear phase. Further, it is suitable for applications where a very low complexity analysis filter bank is required.
