BIDIRECTIONAL BUS REPEATER

摘要

A bus repeater circuit for interconnecting first and second corresponding transmission lines for first and second adjacent bidirectional electrical bus sections. The bus repeater circuit includes first and second current sensors associated with each transmission line to apply a bipolar signal to first and second amplifiers respectively. Output signals from a given sensor of a first polarity indicate that the associated transmission line is transmitting a signal. The associated amplifier couples that signal to the other bus wire. Signals of a second polarity indicate that the associated bus transmission line is not transmitting a signal to the repeater and the associated amplifier provides a corresponding signal, thereby avoiding a latched condition.
