In the current FFT demo, it is possible to right-click on the display and select 'Average'. This will perform low-pass filtering on each FFT bin such that the "noise" averages to its rms value but the signal peaks remain. This is done in the flow graph by using a gr.single_pole_iir_filter as an exponential averager. You can do this in the waterfall mode as well. -- Johnathan Corgan Corgan Enterprises LLC http://corganenterprises.com _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
