AUDIO SWEEP OSCILATOR. This circuit was designed for a sound effect, but may serve other useful purposes when a basic, swept-frequency audio source is required. It produces both square and triangular wave outputs that ascend from about 80 to 730 Hertz in a repeating cycle of about 12 seconds. Appropriate component-value substitutions will yield variations in these parameters.
