ROBUST AND FAST DESIGN OF OPTIMAL COMB FIR FILTERS

摘要

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 de-sign method outperforms the standard procedures in terms of speed and robustness.
