A Study of Efficient Sharpening Based on CIC Filter
Han Xiao-ling · Communication Countermeasures · 2006
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.
