ABSTRACT:
A time division multiplex digital data communication system with reduced band width. The system operates on independent digital signals so they can be multiplexed by encoding the time of transition of the digital data on each channel and transmitting serially the encoded times along with a bit for indicating the direction of transition or state after the transition plus bits for synchronization and/or overhead, as necessary.
