Cic filter order
Webthe output of the fust polyphase CIC filter is the input of the second one’s output, the input data words to the second CIC filter are (BA +1) bits long. As a result, the word length at the second CIC filter’s output, (Bm2+1), is Bm2=[N1 log2 R21+Bd (7) Since R,. = RI RI, the above expression becomes Bm2=[N2 log2 RI+ Binl-(N2 logz RI1-[N ... WebIn the classic paper, “An Economical Class of Digital Filters for Decimation and Interpolation,” Hogenauer introduced an important class of digital filters called “Cascaded Integrator-Comb”, or “CIC” for short (also sometimes called “Hogenauer filters.”) In this tutorial, Matthew Donadio provides a more gentle introduction to ...

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 …
