peak detector can output 1 or 0. What is it outputting?
I get 1 and 0 when it is not freezed.
I uploaded a screenshot, but i am not sure whether this works,

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.
