[sdiy] pwming a tog

[Tom Wiltshire]

Because the standard TOG is based on dividers, you can’t add PWM. Run any width pulse wave through a flip-flop and the output's a square, after all.

That said, there were some TOGs the produced 33% pulse waves rather than squares (not sure exactly what the internals were to do that) but there were none that offered PWM.

If you had twelve ramp oscillators for the top-octave, you could arrange ramp+squares to give you ramps at various divided octaves, and then use those ramps to produce PWM, but it’d be a lot of circuitry, and it’d probably get a bit sensitive. Have a search for “sub-octave ramp wave” to get the basic idea.

HTH,
Tom
