I uploaded a screenshot, but i am not sure whether this works, http://img228.imageshack.us/my.php?image=peakdetected.jpg There you can see that i get 1 at a peak otherwise 0. The blue wave in the scope shows the peaks and the red wave is the signal i am searching peaks for. The signal is at 1020 kHz. Some frequencies results in a freezing of my graphical elements.
Do you think that it might be possible for peak detector to output always the same number at "some frequencies"?
Replace the peak detector with a source of constant 0 or a source of constant 1, do the plots appear frozen?
It seems that if you give the graphical sinks a signal that never changes, the plotted waveforms will also not change.
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.
