Block Filter Architecture for Low-pouter Uniform Finer Banks Implementation

저전력 Uniform 필터 뱅크 구현을 위한 블록 필터 아키텍처

Block filter implementation technique for uniform filter banks is uniform in this paper. By applying block filter into decimation and interpolation filters, it is shown that down and up samplers are cancelled out in respective liters. Furthermore by applying block filters into uniform filter banks, significant reduction for computational complexity is achieved since prototype filter can be shared in each channel implementation. Also, it is shown that proposed implementation is a reconfigurable structure in terms of order variation.
