A simple squelch circuit.
A circuit in a radio receiver that keeps the volume down when no signal is being received, but the volume builds up as soon as a signal is received. The function of a squelch is to adjust the sensitivity of the receiver by eliminating unwanted weak signals that cause background noise such as static, hash, or hiss. Most squelch controls are automatic, but there are a few manual squelch controls, too. Squelch circuits are used in communications equipment, which have long periods of silence between transmissions.
