ABSTRACT:
A range of digital values is assigned to represent a digitized composite signal, while a selected digital value of the range is assigned as a unique dropout sample to represent only a dropout in the signal to the exclusion of signal data. In the event of a dropout, the unique dropout sample is loaded into memory in place of the corresponding incorrect signal data. The unique dropout sample is detected upon read out of data from memory and used to initiate the process of dropout compensation.
