Abstract
Methods of active echo reduction on a multi-drop bus utilizing devices of dynamically-variable impedance, wherein non-signaling intermediate devices are placed in a high-impedance state while all remaining devices are matched to the characteristic impedance of the multi-drop bus. Devices of dynamically-variable impedance capable of implementing methods of active echo reduction on a multi-drop bus are included, as well as systems incorporating such devices.
