Abstract

Presented is a circuit for the generation of low-frequency (0.001 Hz to 63 kHz) sine waves possessing stable amplitude and frequency characteristics using digital techniques. The circuit produces a 32-step approximation to a sine wave at a frequency 1/32nd of the selected digital time-base frequency. Also presented are a crystal-controlled time base to drive the generator, and an active filter for removing the high-order harmonics produced by the generator. Advantages of the digital sine wave generator over analog oscillator techniques are described.
