Control on a radio microphone receiver for fine-tuning the reception according to the surroundings.
A receiver circuit designed to mute (squelch) the audio output when the received signal is too weak to provide acceptable audio or, in some cases, when the wrong signal is being received. See also Noise Squelch, Signal Level Squelch, Tone Coded Squelch.
an electric circuit that cuts off a receiver when the signal becomes weaker than the noise
A circuit used to quiet the output of a receiver when the RF input falls below a pre-determined level
allows you to set the minimum strength signal that will be received.
A communication function that turns receiver amplifier circuits off when noise is the only signal present. In an Ethernet transceiver, this function prevents noise from propagating to all network segments.
To shut off the audio output of a radio when a signal is not being received.
Blocks the unwanted low level hissing noise allowing only the strong incoming signals. It sets the threshold for incoming signals.
a circuit within a radio that keeps the speaker silenced (squelched) until the signal level exceeds a certain point, set by the squelch control. Normally you set the squelch to just block out noise and allow signals to pass.
A circuit that cuts off the output of a receiver when there is no input.
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.
