Synth Circuits

General links and research into synth circuits.

LFO – Low Frequency  Oscillator – One of the basic building blocks of sound circuits.  These are generally well below the audio range ( .3 to 10 Hz) and are more for modulation.  An example of this would be to  modulate the amplitude of a signal to get a tremolo effect or the frequency for a vibrato.



VCO – Voltage Controlled Oscillator
