I am providing pulsed 600v DC to a 500khz tank oscillator which of course rings with a sine wave.
I would like to make that sine wave "dirty" but do not want to make it into a saw-tooth or square wave.. simply "fuzzy" as if there were some vhf interference on it, but still a sine.
I don't mind dropping some of the voltage, so I was wondering about putting a few reverse-biased zener diodes in the circuit for noise.
Will that work? Any better ideas?
