This paper presents a simple method for the design of comb-based decimation filter with a high aliasing rejection and low passband droop. The method is based on the application of the mathematical result on zeros of symmetric polynomials on the unit circle. The application of this result leads to the introduction of the four additional single zeros into comb folding bands, where aliasing occur. As a result, the folding bands become wider and the aliasing rejection is increased. The passband droop is compensated by a simple compensator who works at low rate. The comparisons with the most recent methods from literature confirmed the advantages of this proposal regarding magnitude responses and the required complexity.

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.
