WebR, 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. The normalized version of this last response is the one that the CIC compensator needs to compensate. WebThis overflow is of no consequence. CIC Filter Structure. The filter structures supported by the CIC Interpolation and CIC Decimation blocks exactly match those created by the mfilt.cicinterp and mfilt.cicdecim objects. You can create an mfilt object in any workspace and specify that object in the Multirate filter variable parameter
