Quad Frequency Doubler
Quad frequency doubler, each stage double the signal frequency and are chained together to multiply the signal at the input by 16. Switching jacks allow to break the connection between each stage to use them individually.
One stage can be use to:
– convert a ramp/saw signal to triangle signal
– multiply a triangle signal by a factor of 2
– multiply a sine signal by a factor of 2 (output sine is glitched)
– solarize a video signal
