Hi, Owen,Reading your post a few times, it makes sense ... except for this "knee frequency".
OK, I use some air-cored indusctors in series with +, - and ground but how do I figure out what mH value these need to be?
You mentioned this "thing" called a knee frequency but I don't know:
a) what this is, and
b) how it gives me the right coil value?Can you advise further?
Thanks,
Andy
