Cic interpolation filter
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. WebThe CIC interpolation filter structure consists of N sections of cascaded comb filters, a rate change factor of R, and N sections of cascaded integrators. For more information …

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 WebA CIC lter is nothing but a a succession of N( lter order) moving averages of width RM(Ris the decimation or interpolation factor, and Mis a free integer parameter usually xed to 1 or 2). Each moving average is a very simple FIR de ned as: y n = 1 RM RMX 1 i=0 x n i that is, every output sample is computed as the mean of the RM last input samples.

CIC compensation interpolators are multirate FIR filters that can be cascaded with CIC interpolators to mitigate the drawbacks of the CIC filters. CIC interpolation filters are used in areas that require high interpolation.
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 ...
