Comb filter, optimal filter, FIR filter, equiripple approxima tion, robustness.
An analytical design of digital equiripple comb FIR filters is presented. The filters are optimal in Chebyshev sense. The design runs from the filter specification through the degree formula to the impulse response coefficients, which are evaluated by an efficient algorithm. The proposed design method outperforms the standard procedures in terms of speed and robustness.
