TWIN-T AUDIO SINE WAVE OSCILLATOR. This circuit produces a clean sine wave signal ideal for audio testing, or wherever a good-quality sine voltage source is required. It uses only one integrated circuit which is a common dual operational amplifier, the Texas Instruments TL072CP. The values shown provide an output frequency of about 1000 Hertz. This frequency may be varied over a wide range, using the formula shown in the schematic.
Пример: Infrared control system
