Modified Corrector-Comb-Based Decimator with Improved Passband and Aliasing Rejection
Gordana Jovanović Doleček, Loth M. Barba-Maza · 2019
This paper presents a modified two-stage corrector comb-based decimation structure with an improved magnitude characteristic in all folding bands. This is achieved by inserting a simple multiplierless filter into the first stage of the two-stage corrector-comb-based structure. Additionally, the maximum absolute value of the passband deviation is decreased and it is equal to 0.1 dB, for the cascade of three and four combs, while for the cascade of two and five combs it is equal to 0.2 dB. The method is illustrated with one example. The comparisons with the methods in literature are also included.
