Cascaded Integrator-Comb filters
Overview
Description: Microsemi CoreCIC IP is a highly configurable RTL generator for the decimation or interpolation cascaded integrator-comb (CIC) filters. The CIC filters are widely used in multi-rate signal processing, particularly in up-converters and down-converters, modulators and demodulators, sigma-delta analog to digital converters, and so on. These filters are popular in decimation and interpolation filters where substantial rate change factor is required. The CIC filters provide a linear phase response.
