Abstract
In a receiver system embodying the invention, the amplitude of the input signal is sensed so that when it exceeds a predetermined level, the adaptation of adaptive filters employed in the receiver is inhibited. In one embodiment of the invention the adaptation is inhibited for the extent of time that the sensed signal exceeds the predetermined level. In another embodiment of the invention, the adaptation is inhibited for a fixed period of time whenever the sensed signal exceeds the predetermined level. In still another embodiment of the invention, where the noise impulse has some repetitive pattern, an inhibiting signal is generated in anticipation of a repetitive noise impulse to inhibit adaptation of the adaptive filters during the period of time ('window') the noise impulse occurs.
