Abstract
A transmission system and method for transmission of digital data with impedance matching at the terminal ends reduces reflected signals due to impedance mismatch at the terminating ends and due to impedance transition areas in the transmission line. The transmission system includes a transmission line having a driver end connected to a driving circuit and a receiving end connected to a receiving circuit, each said end having an adjustable termination means connected thereto On the driver end of the transmission line said adjustable termination means is incorporated in the driving circuit, while on the receiver end of the transmission line said adjustable termination means is connected in parallel with the receiving circuit. Thus, both the reflections produced on the ends of a transmission line and the reflections resulting from discontinuities within a transmission line will be terminated.
