Patent ID: 8290457

Claim:
An apparatus comprising: a first impulse detector to receive a desired signal corresponding to a desired channel and to detect an impulse present in a blocking spectrum adjacent the desired channel; a first impulse blanker to receive the desired signal and to blank an impulse present in the blocking spectrum, the first impulse blanker to be operable when no blocker signal is detected in the blocking spectrum; a second impulse detector downstream of the first impulse detector to receive an output of the first impulse blanker and to detect an impulse present in the blocking spectrum; a second impulse blanker downstream of the first impulse blanker to receive the desired signal and to blank an impulse present in the desired signal, the second impulse blanker operable when at least one blocker signal is detected in the blocking spectrum; a prechannel filter to receive the desired signal and to filter the desired signal; and a third impulse blanker coupled to the prechannel filter to receive the filtered desired signal and to blank an impulse present in the desired signal, the third impulse blanker operable when at least one blocker signal is detected in a first portion of the blocking spectrum.
