[sdiy] Timbre Modulator (EN#72) - who needs SAW VCOs?

[Harry Bissell Jr]

Clear and concise schematics involve the designer
understanding how his circuit works, and trying to
convey that sense.

I get thrown by people who draw opamps with the
non-inv
input on the top. I automatically see that as
inverting... and any feedback resistor above the opamp
as negative feedback.

Some people do not take the time to redraw after
making
changes... so their work gets sloppy. It was
inderstandable in the days of sepia and blueprints
(hand drawn) but no longer with CAD systems.

Sometimes concise-ness is sacrificed for form factor..
it has to fit a certain page size or format...
