ABSTRACT:
An impulse noise remover includes: a storage module for storing a plurality of digital values derived from a received signal; a calculating module coupled to the storage module for calculating a first detection value according to a first subset of the plurality of digital values, and for calculating a second detection value according to a second subset of the plurality of digital values; a control unit coupled to the calculating module for identifying a target digital value associated with impulse noise according to the first and the second detection values; and a correcting unit coupled to the storage module and the control unit for replacing the target digital value with a predetermined value.
