Hello, I need again your help for this problem: - I want to locate the peaks (local maximum) of the input signal, which is sinc-function pulse (the 2 gray points in picture sincpuls.png, not the neighbour peaks). How can I use the gr_peak_detector in grc to do this ? which values I should give threshold_factor_rise, threshold_factor_fall, lookahead, alpha ? - If you look at my grc-picture (peakfalse.png) you will see that the peaks are not at the right places. They happen before the true peaks of the sine-function. How comes this ? ( My value for threshold_factor_rise, threshold_factor_fall, lookahead, alpha : 10,10,100,0.001 )
Thanks in advance. grc007 http://old.nabble.com/file/p28919877/sincpuls.png http://old.nabble.com/file/p28919877/peakfalse.png -- View this message in context: http://old.nabble.com/how-to-find-local-peak-of-sinc-function---peak-detector-setup---tp28919877p28919877.html Sent from the GnuRadio mailing list archive at Nabble.com. _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
