摘要
Abstract
The reason of the conventional CIC（Cascade Intergrator Comb） filter＇s undesirable amplitude-frequency response is analysed,and the performance of the CIC filter is enhanced by using a cosine filter and a compensation filter respectively.It is shown in the result of simulation that the stop-band attenuation of the improved CIC filter makes 26dB better than the traditional CIC.Besides the characteristic of the pass-band is modified evidently.The features of its implementation structure suggests that the improved CIC filter is of great significance in the practical application and further study.关键词
