ABSTRACT:
A data transmission system and method includes providing a current to a first conductor by a current source to transmit a first binary digit while isolating a second conductor from the current source. In response to a command to transmit a second binary digit, amount of current provided by the current source to the first conductor is decreased from a maximum value to zero while simultaneously increasing the amount of current provided to the second conductor from zero to a maximum value. The increase and the decrease in the amount of current are done the same rate. A first and a second signal corresponding to the current provided to the first and the second conductors each have a transition edge with a leading section, a midsection and trailing section such that an average slope of the midsection is greater than average slope of the leading section and the average slope of the trailing section.
