[sdiy] SAW core VCO flyback time

[Tom Wiltshire]

How would this work, Rick? I'm not seeing it.

Does it need the two ramps to be running at half the output rate so that you always switch in the middle of the ramp? And don't you just swap flyback time for switching time as the potential glitch?

Thanks,
Tom
