摘要
介绍了对积分梳状滤波器（CIC滤波器）的有效锐化。所提出的锐化滤波器的结构由两个主要部分组成：一个梳状滤波器的级联部分和一个锐化滤波器部分。所提出的方案使得滤波器中锐化部分的工作速率比输入速率大为降低，其频谱响应特性比传统的也有所改进。通过MATLAB仿真，可看出改进锐化后的滤波器性能更优。
This paper proposes an efficient sharpening of a CIC decimation filter. The proposed structure consists of two main sections： a cascade of comb filter, and a sharpened comb filter. This arrangement allows the sharpening operation to move to a lower rate, and the frequency response is improved better than the classic CIC filter, Through MATLAB simulation, we can see the better performance of the proposed filter.
