Two-channel linear-phase FIR filter banks utilizing the frequency-response masking approach
2003 (English)In: European Conference on Circuit Theory and Design,2003, 2003Conference paper (Refereed)
The frequency-response masking (FRM) approach was introduced as a means of generating narrow transition band linear-phase FIR filters with a low arithmetic complexity. This paper proposes an approach for synthesizing two-channel maximally decimated FIR filter banks utilizing the FRM technique. Compared to conventional quadrature-mirror filter (QMF) banks, the proposed banks lower significantly the overall arithmetic complexity at the expense of a somewhat increased overall filter bank delay in applications demanding narrow transition bands. Examples are included illustrating the benefits provided by the proposed filter banks.
