Analog oscillators produce excellent sine waves, but they aretemperamental and very hard to design. Also, analog oscillatorsrequire extensive redesign every time the oscillation frequencyis changed. Digital oscillators are easier to designthan analog oscillators, and digital signals already exist indigital systems, so it is often cost effective to derive sinewaves from digital signals. The circuit described here derivesa sine wave, whose frequency is 1/32nd of the input, fromalmost any periodic digital input signal.
