Hi, I have a simple FM broadcast receiver flowgraph in c++ that causes overruns. I'm using a B100 with a wbx daughter board. The flowgraph is
usrp source -> lowpass filter -> quad demod -> deemphasis -> audio lp filter -> constant multiply -> audio sink The sample rate is 250K. It works but after a couple of seconds the overruns start. I've used much more complicated flowgraphs than this with much higher sampling rates with out overruns. Looking at the cpu utilization shows each core at less than 5%. Would anyone have any suggestions for what to look at that could be causing the problem? thanks, stephen _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
