摘要

级联积分器梳状滤波器是通信系统中常用的一级抽取滤波器。本文回顾了锐化技术用于纠正这些滤波器频率响应中存在的通带“下垂”。在现有技术的基础上，提出了一种允许部分非递归(因此可能具有更高的速度)实现的CIC滤波器，具有两个抽取比的功率。

Sharpening of partially non-recursive CIC decimation filters

The cascaded integrator comb filter is commonly used as a first stage decimation filter in communications systems. This paper reviews sharpening techniques for correcting the passband 'droop' present in the frequency response of these filters. A variation on an existing technique that would allow a partially non-recursive (and, therefore, potentially higher speed) implementation is presented for CIC filters with power of two decimation ratios.
