Quote:You get a nice clean sine wave from the injector - nominally 1KHz, but as often as not it's a bit higher than that. Not important, it has harmonics going way up in frequency anyway.
Puzzled. If it's a clean sinewave the harmonics will be minimal. The schematic shows a classic phase shift oscillator which generates a sine wave that's realtively clean and free of harmonics. https://en.wikipedia.org/wiki/Phase-shift_oscillator
