Novel droop-compensated comb decimation filter with improved alias rejections

Authors:  Gordana Jovanovic Dolecek, Alfonso Fernandez-Vazquez

Abstract:
This paper presents a novel two-stage comb decimator with the improved magnitude characteristic. Simple multiplierless corrector filters, which are designed using the frequency sampling and IFIR methods, are introduced. The proposed filters compensate the comb passband droop in the wideband passband region and increase the attenuations in the folding bands. Using the multirate identity the filters may be moved to a lower rate. The filter design depends only on the number of the cascaded comb filters and do not depend on the decimation factor M.
