Low power non-recursive comb-based structure with improved magnitude response

Abstract

This paper presents a low power comb-based nonrecursive structure with improved alias rejections and a decreased passband droop. The passband is improved by introducing a simple compensation filter at low rate. The cascaded cosine filters are used to improve the alias rejections in the folding bands. We consider the case in which the decimation factor is a power of two. The comparisons with some non-recursive structures are also provided.
