Title: Spacial derivative bus encoder and decoder

Abstract: A method and apparatus for providing efficient and accurate electronic data transmission of information on a data bus in the presence of noise. Data signals are received on a plurality of input lines by a spacial derivative encoder. The spacial derivative encoder encodes the signals and transmits them to a receiver having a spacial derivative decoder. The spacial derivative decoder then decodes the signals. Minimal overhead is required as for n input lines only n+1 lines are needed to transmit each of the encoded signals.
