Abstract :
New multiplication-free FIR digital filters are introduced to replace the masking filter in narrowband frequency response masking (NBFRM) based filter. The proposed filters not only significantly improve the computational efficiency of NBFRM filters but also minimize the increment of the group delays compared with existing NBFRM design techniques.
