Hi,
i already spend much time, trying to find actual information, on how noise is exactly generated. To me its not enough, that "big loops catch noise" or "use a short lead". I want to know exactly where the noise is really created. Where is the current flowing that creates the noise? Through which parts?
Some learning experiments would be good also. Or maybe there is a good book about it?
I found this video, which i deem to have quite some competence in it, but its not an educational video unfortunately:
