Abstract
A two-way transmission system including a master station coupled to a transmitting end of a transmission line and a sub station coupled to the receiving end of the transmission line. A pulse transformer is provided between the transmission line and at least one of the master and sub stations. Variations in current flowing through the winding of the pulse transformer coupled to the transmission line produce variations in the impedance of the secondary winding which are detected with a comparator circuit to produce an output received signal. A diode may be inserted in series with the transmission line at at least one of the receiving and transmitting ends of the transmission line to prevent the charging of the distributed capacitance of the transmission line to increase the maximum possible transmission rate.
