Design of very sharp recursive digital filters using the frequency response masking technique

This thesis focuses on designing infinite-impulse response (IIR) digital filters based on the frequency response masking (FRM) approach. The proposed method is different from previous methods of designing IIR digital filters based on FRM approach in both structural and algorithmic aspects. In this t...

The proposed method is different from previous methods of designing IIR digital filters based on FRM approach in both structural and algorithmic aspects. In this thesis, both the bandedge shaping filters and masking filters are recursive filters realized in the form of wave digital filters.
