Abstract
A technique is used by a squelch circuit (,) that generates a fast squelch. The technique involves generating a noise signal (,) from a demodulated signal (,), generating a squelch check request (,) of one of two types, performing a release (,) of a reset control (,) in response to the squelch check request, generating an integrated noise signal (,) having essentially no decay rate from the noise signal starting at the release of the reset control, generating a result of a comparison (,) of the integrated noise signal to one of two values corresponding to the one of two types of squelch check requests at an expiration of a predetermined delay started at the release of the reset control, and controlling a muting (,) of a speaker (,) in response to the comparison.
