Conference Paper: Sharpening of partially non-recursive CIC decimation filters[Show abstract] [Hide abstract]
ABSTRACT: The cascaded integrator comb filter is commonly used as a first stage decimation filter in communications systems. This paper reviews sharpening techniques for correcting the passband 'droop' present in the frequency response of these filters. A variation on an existing technique that would allow a partially non-recursive (and, therefore, potentially higher speed) implementation is presented for CIC filters with power of two decimation ratios.

ABSTRACT: A modification of an existing technique is presented which compensates for passband droop in the frequency response of cascaded integrator comb (CIC) filters for power-of-two decimation factors. The new technique delivers passband droop correction comparable to existing techniques, while allowing faster operation than for existing structures by moving integrator sections away from the filter input.
