Fifth type of comb FIR filters
Pavel Zahradník, Boris Šimák, Miroslav Vlček · 2011
An extension of the design of digital equiripple comb FIR filters is presented. We introduce the fifth type of comb FIR filter which complements the existing four standard types. The design runs from the filter specifications through the degree formula to the impulse response coefficients, which are evaluated by an efficient recursive algorithm. One example is included.
