CIC Decimation Filter for Frequency

Rajesh Kumar Dubey, Kamal Prakash Pandey, Dr. Rakesh Kumar Singh

Abstract: The CIC filters do not require any multiplier circuits and hence are very economical for implementation in hardware and the problems with cascading faced by the accumulate and dump circuit are also overcome with the CIC design. The frequency response of CIC filters has a poor in band frequency response and are mostly used to reduce the decimation factor by large ratio while suitable response sharpening filters work at the reduced rate to get the desired characteristics
