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.

It’s a type of AC track circuit in which audio frequency signals are used instead of pure AC or DC signals. Its generally a joint less track circuit, extremity of the tracks are defined by tuned units but can also be used with IRJs. it is least prune to interference and hence can be used in ac, dc, and non electrified areas.
