ABSTRACT:
Apparatus is described for balancing a two wire, full duplex data transmission system. In the described system a transmitter and receiver in one station are connected to a transmitter and receiver in another station by means of two lines. The two lines carry transmitted data signals, and the transmitters in each station are connected to the receiver in the same station by a dummy circuit. The balancing operation is performed in a dummy circuit comprising a plurality of parallel-connected current paths, each path including a series combination of a time stage and an amplitude stage for adjusting the amplitude and phase relation to the data signal of subsidiary current flowing therethrough. The sum of the subsidiary currents flowing through the parallel paths from the transmitter via the dummy circuit to the receiver in the same station is adjusted to be equal to the current flowing from the transmitter via the lines to the receiver in the same station.
