Simple mixer implementation? #459

Open tt-aqt opened 2 years ago

I want to use pyrpl to drive a LC retarder as a noise eater. These need a symmetric square wave drive, I think. But I cannot find a way to modulate the amplitude of a square wave with a PID output? I only have one input and one output free. I don't have the space for an external square generator and mixer.
