PRECISION_AUDIO_WAVEFORM_GENERATOR

Published:2009/7/7 1:19:00 Author:May | From:SeekIC

This circuit generates sinusoidal, square, and triangle waveforms simultaneously. Set the frequency to a particular value or vary it, as shown above. An op amp can be added for extra drive capability and simpli-fied amplitude adjustment. A simple comparator, slicing the triangle waveform, provides continuous duty cycle adjustment at a constant frequency.
