チ回路。In a squelch circuit that has hysteresis between the squelch activation and squelch cancellation levels of a wireless communication device where a data signal is transmitted prior to a voice signal, when the data signal is received, a trigger pulse is generated to terminate the activated squelch. A squelch circuit characterized in that a means for forcibly releasing the signal is added.
