Hi Scott,

I wonder, was his idea based on the work of Nakayama (US patent 4595883, 1984/1986) or just the other way around? Below Nakayama's class-I OPS, exactly the same as the one by Kendall.

Cheers,
E.

Never saw this, have no idea. I have to admit fortuitous coincidence at that detailed a level is a stretch.

More on this subject can be found here and here, as well as other implementations of geometric mean biasing circuits with error feedback.

Cheers,

It's coming along fine John, pub date 1 April.
Will have some nice low-signal-level applications.
Correction filter to correct for cartridge mechanical resonance.
Good stuff!

I wish all of you and your loved ones a very Merry Christmas and a happy, healthy and prosperous 2012!

6500 words and counting 20+ figures I hope it fits! My computer woes have been amazing, literally as I started final edits I was hit by the XP 2012 malware luckily we have plenty of backups and I managed to save everything. Oh yea, there will be a part 3 on calibration techniques.

Same to you!

It was like a scene from a sci-fi movie. I found an old desk top machine that had not been booted in over two years, I turned it on it died, again it blue screened in 5 min. finally it sat overnight updating and re-booting and the next day I was running again.
