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.

The circuit works on the principle of just using op amps. The LM324 is a quad op amp, meaning it's composed of 4 independent op amps. In this circuit, the first op amp produces a square wave. After that, the circuit uses 2 integrator circuits to convert the square wave into triangle and sine wave signals. Below we show how to build the circuit.
