Efficient Technique for Improving the Frequency Response of CIC Compensation

This paper presents a new method to improve the frequency response of CIC compensation filter. After the CIC filter cascaded the fir filter which has inversed magnitude response to CIC compensation filter was proposed, which improved the pass band and the transition band features of the CIC filter and improved the performance of CIC compensation filter. The decimation factor introduced. It presents new CIC compensation filter to compensate for CIC filter that pass band flatness is improve .Here we used three coefficients so less computation is required .Th exhibits small passband droop in comparison to CIC filter. running the compensation filter at the low rate is achieve more efficient hardware solution that is m sharing in the compensation filter. This filter is design using FDA
