Cic filter order
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.

WebOct 3, 2016 · Signal decimation using a compensated CIC filter. Decimation is the process of converting a time-domain signal sampled at frequency fs f s into a signal sampled at frequency fs/R f s / R, where R R is the decimation rate. Downsampling alone, i.e. keeping one sample every R R samples is not sufficient. A low-pass filtering step must …
