WebThe CIC Interpolation block performs a sample rate increase (interpolation) on an input signal by an integer factor. Cascaded integrator-comb (CIC) filters are a class of linear phase FIR filters that consist of a comb part and an integrator part. The CIC Interpolation block requires a Fixed-Point Designer™ license.

WebThe response of a CIC filter is given by: H c i c ( ω) = [ sin ( R D ω 2) sin ( ω 2)] N. R, D, and N are the rate change factor, the differential delay, and the number of sections in the CIC filter, respectively. After decimation, the CIC response has the form: H c i c ( ω) = [ sin ( D ω 2) sin ( ω 2 R)] N. WebMar 7, 2024 · Various modifications have been suggested in literature to improve the frequency response of CIC decimation filters which revolve around the conventional decimation filter .
