I'd start by reading some articles or books that describe CIC filters and how to use them. Once you understand that well then applying it to a modulator should be straightforward. Eric Jacobsen Minister of Algorithms Abineau Communications http://www.ericjacobsen.org

Best place to start is to read the datasheets for cic on altera and/or xilinx websites. -Clark
