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.

ECHO TONE OSCILLATOR. This simple circuit amplitude-modulates a single tone in such a manner to approximate the echo effect one might obtain, for instance, with sonar apparatus. Any reader who has been on a sonar-equipped vessel will realize that some imagination is required to appreciate the similarities among this simple scheme and the "real thing." However, this circuit might adjunct a small model (of a submarine, perhaps) to add the dimension of sound.

SCR oscillator. Silicon controlled rectifiers (SCR) can easily oscillate if there is an inductor (a speaker coil in this case) which gives just enough extra voltage to completely switch off the sustain current. (simple)
