Fractional-Delay and Supersymmetric Mth-Band Linear-Phase FIR Filters Utilizing Partially Symmetric and Antisymmetric Impulse Responses

• This brief considers fractional-delay finite-length impulse response (FIR) filters and a class of supersymmetric Mth-band linear-phase FIR filters utilizing partially symmetric and partially antisymmetric impulse responses. Design examples reveal significant multiplication savings, depending on the specification, as compared to traditional filters.
