Abstract

This paper presents a simple multiplierless two-stage comb decimation filter. The filter exhibits an improved magnitude characteristic in both pass band and comb folding bands. The attenuation in folding bands is increased by inserting additional zeros into comb folding bands, which are provided by two additional combs at the second stage. The comb pass band droop is decreased by cascading a simple compensator at low rate. The corresponding structure is simple and can be implemented either in nonrecursive or recursive form as CIC (Cascaded-Integrator-Comb) filter. The comparisons with some existing comb-based decimation filters demonstrate benefits of the proposed method.
