frequency generators. 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.

Signal Generator. Low Distortion Signal Generator. Part 1. Sometime around 1982 I designed a variable frequency audio signal generator, called the AFG/3, with a range from 10Hz to 100kHz and sinewave, squarewave and toneburst outputs. There were switched ranges from 0-3V down to 0-3mV, and a constant 600R output impedance.
