Abstract
To compensate for transmission errors of a non-ideal system for transmitting digital signals, first signal deviations are determined and stored, and then there is a direct processing of the input signals into output signals by combining the input signals with the stored signal deviations. The invention includes both method and apparatus and provides a substantial reduction in equipment costs.
