ABSTRACT:
The noise blanker of a conventional FM radio is inhibited for several seconds upon closing of the receiver's squelch gate. Following the inhibit period, the blanker is reactivated and again inhibited for the full period upon a subsequent squelch gate closing. Thus, the blanker is inhibited for those signal conditions in which its operation would degrade the overall intelligibility of the processed signal as determined by the squelch control setting.
