Re: Pease tuneable MFB band-pass filter

I gave not seen RAP's original article. I looked the circuit up using John Woodgate's citation: "Analog Circuits: World Class Designs", edited by Bob Pease, page 236, "Multiple Feedback Bandpass Filter", in a chapter written by Steve Winder.

This is a recent article, and I know from experience that the EDN
editors encourage writers to supply their own diagrams, at least for
their "Design Ideas". Perhaps main articles are different. But given
the error in the article name, anything's possible.
