“…The numbers of APOS for the comparison methods and the proposed method are compared in the first column. In all comparisons, except with the method in Jovanovic Dolecek and de la Rosa, 12 the proposed method requires lesser number of APOS. However, the method in Jovanovic Dolecek and de la Rosa 12 is dedicated only to the comb passband improvement.…”

This paper presents a theoretical background for design of comb decimator based on theorem of symmetric polynomials with roots on the unit circle. A simple multiplierless filter, called zero‐separation (ZS) filter, which separates doubled comb zeros, is derived. The separation of doubled comb zeros improves comb aliasing rejection. In order to get more benefits of the ZS filter, a two‐stage structure is considered. The classic comb filters are in both stages of the proposed structure. Additionally, in the second stage, a ZS filter is inserted to improve comb aliasing rejection. The passband droop is compensated by the compensator which works at low rate and is designed using particle swarm optimization (PSO). The method is illustrated with various examples. The comparisons with methods from literature prove the benefits of the proposed work.
