sine shapers & update

[Martin Czech]

Long forgotten:

http://www.geocities.com/SoHo/Museum/4459

under "Do it yourself Synthesizer" 

you'll find "Sineshapers".

It's not complete, but there's an error estimation
for the well know overdriven differential stage approach
(showing that it is not so good).

And as an extension of this simple differential stage thing there
are some scans from an IEEE paper about Analog Devices precision
sine shaper which show the basic ideas. Ok we have to go discrete,
we have no common centroid ultra matched npn, nevertheless this
could be interesting. No, I was not drunk when I scanned these
papers, I really don't know why they are so twisted ;>.



The other methods will follow some time.

By the way:

I've added some new links to the "Synth DIY Grey Pages".


under "The Synth DIY Grey Pages"

as well as the mail archive for 10.98.


.... and the whole layout is now a bit more good looking.

NO FRAMES anymore!
