PROGRAMMABLE_FREQUENCY_SINE_WAVE_OSCILLATOR

Published:2009/7/9 1:26:00 Author:May | From:SeekIC

This Wien-bridge oscillator is very popular for signal generators, since it is easily turned over a wide frequency range, and has a very low distortion sine-wave output. The frequency determining networks can be designed from about 10 Hz to greater than 1 MHz; the output level is about 6.0-V rms. By substituting a programmable attenuator for the buffer amplifier, a very versatile sine-wave source for automatic testing, etc. can be constructed.
