Abstract :
New structures combining the frequency-response masking (FRM) and the single filter frequency masking (SFFM) techniques are presented for the design of arbitrary bandwidth sharp FIR filters. The newly introduced SFFM-FRM structures reduce the number of masking filters from two to one and yield significant savings in the number of arithmetic operations. The design example shows that the proposed filter leads to more than 35% savings in the number of multipliers compared with the original single-stage FRM approach
