Alignment Advice.

[Mark Hennessy]

Don't worry about it, Mark. I only started playing about as Al had asked about the inductance. It does what I want it to whatever the numbers are.

I wasn't sure why you needed to know, but I guess it's a useful learning exercise if nothing else.

If curiosity still bites, try connecting the loop across the output - you'll now have a high-pass filter with Zout forming the resistance. You might need to add to Zout, depending on the values. Ideally, we want a nice "passband" at the high frequencies, then a clear "rollover", and the -3dB point. If you can observe these, then we can calculate L.

It's what we're doing this morning at work, by coincidence...
