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. WebTherefore, it would be interesting to see how low group delay filters perform in comparison with classic linear FIR filter within multiple constraints such as cost, signal to noise ratio …

WebDifferential delay. Specify the differential delay of your CIC filter as an integer value greater than or equal to 1. The default value is 1. The differential delay changes the shape, number, and location of nulls in the filter response. Increasing the differential delay increases the sharpness of the nulls and the response between the nulls. WebAn important issue in many applications is the delay associated with the processing of a signal. A common measure of delay is the group delay deﬁned as t=−df/dv.
