Abstract
A data transmission system for transmitting and receiving data over a transmission line includes a receiving station having a receiving circuit for simultaneously detecting current and voltage signals including the data in the transmission line and applying these signals to a common output impedance, so that an output voltage signal developed across the output impedance will have a sufficient signal level irrespective of the value of other load impedances on the transmission line.
