ABSTRACT:
A technique for improving the quality of digital signals in a multi-level signaling system is disclosed. In one particular exemplary embodiment, the technique may be realized as a method for improving the quality of transmitted digital signals in a multi-level signaling system wherein digital signals representing more than one bit of information may be transmitted at more than two signal levels on a single transmission medium. The method comprises encoding digital values represented by sets of N bits to provide corresponding sets of P symbols, wherein each set of P symbols is selected to eliminate full-swing transitions between successive digital signal transmissions. The method also comprises transmitting the sets of P symbols.
