A squelch circuit turns off the audio input to the speaker when there is no radio signal being received. This stops the speaker from producing annoying noise when no radio signal is being received.

What is squelch?
Squelch is something used in telecommunications, squelch is a circuit function that acts to suppress the audio (or video) output of a receiver in the absence of a sufficiently strong desired input signal. For instance if you turn the squelch up on a radio you can cut out the noise but if someone transmits they will pass the squelch threshold and be heard.
What are the Applications of acceptor circuit?
There are many applications of this acceptor circuit. You can learn more about them with some electrical training programs.
What are the applications of a monostable multivibrator?
applications of monostable multivibratorA monostable is a circuit that will respond to a stimuli only once and only for a period. Its usage can be many depends of applications
What are the applications of fixed bias amplifier circuit?
low input impedance
What are the applications of single tuned coupled circuits?
The resonance effect of the LC circuit has many important applications in signal processing and communications systems.The most common application of tank circuits is tuning radio transmitters and receivers. For example, when we tune a radio to a particular station, the LC circuits are set at resonance for that particular carrier frequency.A series resonant circuit provides voltage magnification.A parallel resonant circuit provides current magnification.A parallel resonant circuit can be used as load impedance in output circuits of RF amplifiers. Due to high impedance, the gain of amplifier is maximum at resonant frequency.Both parallel and series resonant circuits are used in induction heating.LC circuits behave as electronic resonators, which are a key component in many applications:AmplifiersOscillatorsFiltersTuners
What is the purpose of a squuelch circuit?
A squelch circuit is installed in a radio communications receiver to shut down the output when no speech is being received, in order to suppress interference noises. All airborne VHF/UHF communications receivers have them.
Is squelch circuit in radio receiver used to catch weak signals?
No. The squelch circuit is used to mute the background noise when no signal is received. You could try to catch weak signals by disabling the squelch.
