Abstract
A television receiver for receiving TV signals when unknown interference is present in a predetermined bandwidth in which the TV signals are transmitted. The TV receiver comprises an input, a tuner, a configurable filter and a controller circuitry. The input receives a radio frequency (RF) signal comprising the terrestrial TV signals. The tuner is configured to detect the terrestrial TV signals, where the terrestrial TV signals include a plurality of frequency channels within a predetermined bandwidth and the plurality of frequency channels provide TV signals which communicate TV channels. The configurable filter is configurable to suppress signals received from one or more of the plurality of frequency channels within the predetermined bandwidth. The controller circuitry is operable to form a channel map of the TV channels detected by the tuner for selection by a user of the television set and consequent upon a TV channel not being detected on a frequency channel, configure the frequency domain filter to suppress signals received from the frequency channel.
