Decimation reduces the sample rate of the incoming sequence to a lower rate. You can find more information about the DDC on the wiki. http://gnuradio.org/redmine/wiki/1/UsrpFAQDDC How you set the decimation rate depends on how you use gnuradio. You may want to look at the following usrp interface file. usrp/host/include/usrp/usrp_standard.h Thomas _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
