Webinverse of the CIC filter can be applied to achieve frequency response correction. Such filters are called “compensation filters.” For data rate down conversion, the compensation filter follows the CIC filter. For up sampling systems, the compensation FIR filter pre-conditions the data and is followed by a CIC filter. In other words, the WebSep 30, 2016 · The CIC filter which is also denoted as recursive running sum filter is indeed a special implementation of a moving-average filter. The moving average filter is y [ n] = 1 D [ 1 + z − 1 + z − 2 + ⋯ z − D + 1] = 1 D ∑ n = 0 D − 1 z − n = 1 D 1 − z − D 1 − z − 1 which can be implemented by a D -tap FIR filter.

Therefore, CIC filters are more efficient than conventional FIR filters, especially in fixed-point applications [3].CIC filters were invented by Eugene B. Hogenauer, and are a …
Webof the parallel CIC filters and linear interpolation filter. Note that the former response is a periodical whereas the latter is not. The frequency response of the parallel CIC filter stage is simply the same as the response of one CIC filter given by Eq. (1), where, however, R has to be replaced by Rint. Since the linear interpolation is done at WebCIC filters are an optimized class of linear phase FIR filters composed of a comb part and an integrator part. The CIC interpolation filter is conceptually given by an upsampler followed by a single rate CIC filter, H(z), which is a lowpass anti-imaging filter. The CIC interpolation filter increases the sample rate of an input signal by an ...
