METHOD AND APPARATUS FOR PREVENTION OF SQUELCH CHATTER

摘要

A squelch circuit (118) is provided having a squelch hysteresis window for preventing squelch chatter in a communication device (100). The communication device (100) includes a plurality of squelch states. The squelch circuit (118) comprises a first means (206) for sensing when the communication device (100) is in a first squelch state. The squelch circuit (118) also includes a second means (116) which is responsive to the first means (206) for varying the squelch hysteresis window to prevent squelch chatter.
