Abstract
A signal quality detector (200) determines the quality of an incoming received data signal within a communication device (100). The audio output of the communication device is muted and unmuted according to the decision of the signal quality detector (200). The signal quality detector (200) allows the threshold length of an invalid bit period (210), along with the number of invalid bit periods detected (220), to be used to vary the decision sensitivity of the detector.
