46. 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.
