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 … WebA CIC interpolator would be N cascaded comb stages running at fs R, followed be a zero-stu er, followed by Ncascaded integrator stages running at f s.
