Abstract
A bidirectional digital communication circuit and a bidirectional digital communication method for combining multi-channel signals to a duplex digital communication system apply time division multiplexing. The signals can be unidirectional and bidirectional; signals relationship is not necessary. The direction detector circuit determines signal directional automatically to avoid the signal loop. It's suitable for applying to fiber, cable or wireless communication system which is needed to minimize the communication channels.
