ABSTRACT:
Compensation for offset errors caused by data truncation is accomplished by adding a compensation value to processed data in systems where the truncation stages are arranged in determinable configurations. More than one compensation value may be selected and applied. The selection of the appropriate value is determined by the number and type of truncation stages used in a given system configuration. The compensation value may be predetermined or measured.
