Patent ID: 7167523

Claim:
A method of transmitting n signals over transmission lines to a receiver, wherein n is an integer greater than one and wherein the n signals include signals IN( 0 ) through IN(n−1), the method comprising: providing a first and a second reference voltage; and encoding the n signals into n+1 encoded signals comprising signals enc( 0 ) through enc(n), wherein encoding comprises: determining the difference between the first reference voltage and signal TN( 0 ) and generating a signal enc( 0 ) as a function of the difference between the first reference voltage and signal IN( 0 ); for I from 1 to (n−1) determining the difference between signal IN(I−1) and signal IN(I) and generating a signal enc(I) as a function of the difference between signal IN(I−1) and signal IN(I); determining the difference between the second reference voltage and signal lN(n−1) and generating a signal enc(n) as a function of the difference between the second reference voltage and signal IN(n−1); and concurrently driving n+1 encoded signals enc( 0 ) through enc(n) on separate output transmission lines to the receiver; and decoding the n+1 encoded signals enc( 0 ) through enc(n) received at the receiver into n output signals that correspond to signals IN( 0 ) through IN(n−1).
