Abstract
An improvement in a bus where the propagation time between two of the transmitters on the bus is appreciable compared to the period of the bus cycles. High impedance drivers are used by the transmitters to permit signals on the bus to be superimposed on one another. This permits signals from one transmitter to be propagated even when that transmission occurs while another signal is propagating past that transmitter.
