Paper Title
Performance Enhancement Of CIC Filters

Abstract- This paper presents comparison between CIC filter, sharpened CIC filter and modified sharpened CIC filter. It also gives comparison between cascaded CIC cosine filter, modified cascaded CIC cosine filter and modified cascaded CIC cosine filter with compensator for a decimation factor of 64. Techniques like compensation, cosine prefilters and sharpening of CIC filters enhance the performance characteristics of CIC filters. Narrowband compensation technique improves the passband characteristics, cosine prefilters improve the stopband characteristics and sharpening improves both i.e passband and stopband. Multistage realization furthur improves the performance characteristics of the enhancement techniques.
