Audio Frequency Generator Circuit - ElectroSchematics.com
https://www.electroschematics.com/audio-frequency-generator/
This audio frequency generator is a triggered signal generator. When a positive pulse of about 6 volts (minimum) is fed to the circuits input , a modulated audio signal comes out of the output. The signal pattern is similar to a bird’s chirp. The pulse width of the trigger signal must be a minimum of 2.5 miliseconds.
