[sdiy] CMOS Saw to Triangle Waveshaper (corrected URL)

[Scott Gravenhorst]

I sit corrected.  I don't remember where I picked
that up.  Good to know you guys are watching...
Gotta watch *me* like a hawk.  I'll fix the text.
I wrote a VB program that has a bunch of sliders
for harmonics' levels.  It graphs the resulting
wave from the sliders as the coefficients of the 
sine terms.  I'll have to plug your numbers in.  
That way, I'll remember it.

René's original circuit shows an expo input.
