Hello AAC -
I am trying to design a circuit that takes a waveform and only leaves the peak, with some variability of how much of the peak is passed. Not exactly a clipping circuit, not exactly a peak detector.
This is the closest I could get: http://tinyurl.com/y7rbzxt7
But it's not ideal for a variety of reasons. The incoming waveform is 10v, the potentiometer has a range of 0-12v - so I'm not sure why I can't get to a resolution that totally nulls the incoming waveform. I'm also using a buffer for the variable voltage threshold - because I can't seem to get it to work any other way - but I feel like there should be a way around that, right?
Can anyone help set me on the right path?
