The Mini-3 LFOs & Noise
The LFOs are op-amp interegrators providing square and triangle waveforms
for low frequency modulation. As the feedback is increased by lowering the
resistance of the 100K POT the .1 capicator charges faster increasing the
frequency.
The noise curcit is a noisey transistor and a op-amp amplifier.
Testing The LFOs
Apply +- 12VDC to the curcit, then hook the output to a analog meter.
The frequency of the oscillator should increase/decrease when the 100K pot is ajusted.
The output of the noise curcit should be connected to a monitor amp and should sound noisey.
