ABSTRACT:
A communication system having communicating devices coupled to a closed loop bus substantially reduces interconnect distances and corresponding signal propagation delays between the devices. Particular devices possess switchable impedance elements that can be selectively actuated to produce an effective terminating impedance substantially at a midpoint position along the closed loop from the coupling point of a transmission device. In such an arrangement, the produced effective terminating impedance would cause the signal transmitted by the transmission device to propagate to a destination device substantially without signal degradation due to signal reflections.
