Seema Chaudhary, N. N. Tripathi · 2012
This paper presents a new method to improve the fre quency response of CIC compensation filter. After t he CIC filter casca ded the fir filter which has inversed magnitude res ponse to CIC compensation filter was proposed, whic h improved the pass band and the transition band feat ures of the CIC filter and improved the performance of CIC compensation filter. The decimation factor introduced. It presents new CIC compensation filte r to compensate for CIC filter that pass band flatn ess is improve .Here we used three coefficients so less computatio n 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 tools. Keyword : CIC filter, Fir filter, Compensation filter
