Audio Oscillator Circuits

  

Audio oscillators are electronic circuits that produces a repetitive, oscillating electronic signal, often a sine wave or a square wave. These Oscillators convert direct DC current from the power supply to an alternating current signal. They are used in many electronic devices. Common examples of signals generated by oscillators include signals broadcast by radio and television transmitters, clock signals that regulate computers and quartz clocks, and the sounds produced by electronic beepers or video games.

All audio oscillator circuits produces frequencies in the audio range, about 16 Hz to 20 kHz. A low-frequency oscillator (LFO) is an electronic oscillator that generates a frequency below ≈20 Hz. This term is typically used in the field of audio synthesizers, to distinguish it from an audio frequency oscillator.
