Abstract
Method, system and computer program product for replacing a portion of a digital signal by applying a first difference correction that, after range limiting, converts the samples in the replacement portion to extremum values; then applying a second difference correction based on the difference between the extremum values and the desired replacement values. The first and second sets of correction values are thus independent of the original values in the first digital signal.
