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. WebHere's the frequency response plot for the filter. For details about the transfer function used to produce the frequency response, refer to [1] in the References section.
