I believe this is implemented as described as a linear phase DC blocker in this paper: http://www.digitalsignallabs.com/dcblock.pdf I believe the "length" parameter is the "D" parameter in the moving average calculations. Hopefully this helps. Brian _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
