Abstract
A novel computationally efficient realization of sharp linear-phase fi nite impulse response (FIR) bandstop filters is proposed. The synthesi s scheme for the bandstop filters is derived from variations of the fr equency-response-masking technique. Five realization structures are pr esented in this paper for the synthesis of five different classes of b andstop filters. Approximate expressions for the optimal value of the impulse response up-sampling ratio (M) and the corresponding number of multipliers are derived.
