The Peakdetector(with TH factor Rise and Fall) works and the Peakdetector2 works not. Maybe there are some bugs in the peakdetector2 (with only TH factor Rise).

Yes i did this and also other combinations, but only when i play with Peakdetecor2, my application freezes. > > It seems that if you give the graphical sinks a signal that never > changes, the plotted waveforms will also not change. My application is really freezed. I changed the signal frequency, so i can watch how the signal in the scope changes, but when i change to special frequencies, then i get my application freezed. > > Further, if your scope is triggering on channel 1 (the blue) and blue is > constant, the scope cannot find a trigger point, and stop plotting new > samples until a trigger point is found. I tried this also, but this doesnt solve this problem. As i said this problem doe not appear in Pekdetector but in Peakdetector2. Further on the Peakdetecor finds peaks whether i changed the TH factor Rise to 10e15. :-) It would be nice if you give me some instructions for the alpha value and look ahead. Because i think i missunderstood the documentation of the peakdetector. Will there be always an average value calculated or only when the threshold founds some possible peak ? Can you please explpain in your own words the alpha value ? regards markus _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
