Analytical design of optimal FIR comb filters
Pavel Zahradník, Miroslav Vlček · 2004
Novel analytical method for the design of digital optimal equiripple FIR comb filters is presented. The filters are optimal in Chebyshev sense. The numbers of notch bands, the width of the notch bands and the attenuation in the passbands can be specified. The degree formula is presented. One example demonstrates the efficiency of the filter design.
