I have made the PIPP limiter on a separate board and it is pleasingly symmetrical or would’ve been if I had built it more carefully

@synx508 All it needs now is a seat, a steering wheel and a set of wheels. And a rear screen wiper...

(By the way, what IS a PIPP limiter?)

@apenkop It's a limiter that adjusts the gain independently for the positive and negative half cycles of the signal waveform.
@synx508 Ah! I recently saw a video about electromagnetic waves, so that rings a bell. Great work!
