Digitally Controlled Oscillator (DCO)

The microprocessor-controlled sound generator used in a digital synthesizer. The DCO directly generates the original signal that is used as the fundamental for the sounds created by the synthesizer. The keyboard tells the DCOs what pitch to produce; the audio signal may then be altered by sound modifiers, including a DCWDCAdifferentiators and integrators, and various modulators and limiters. The digital equivalent of the analog VCO.
