Abstract
When combining digital data sets in the time domain into a combined digital data set a subset of samples of each digital data set is adjusted to enable unraveling the data when decoding. To enable correction during decoding of an error introduced by the adjustment, an error approximation is stored for each adjusted sample. A set of error approximations is created which is indexed allowing substantial reduction in size of the error approximations to be stored for the adjusted samples. Instead of creating a set of error approximations for each combined digital data set one set of error approximations is created based on the errors introduced when creating multiple combined digital data sets.
