FIELD: information technologies.
SUBSTANCE: first pole of a supply voltage source is connected to the first pole of the double-wire communication line via the first resistor, and the second pole of the supply voltage source is connected with the second wire of the double-wire communication line via the second resistor. Besides, the first and the second resistors have equal values of resistance, and the receiver is connected to the double-wire communication line between the receiver and the supply voltage source and is equipped with two current sensors. A signal of reading is determined as a sum of absolute values of measured currents.
EFFECT: increased distance and reliability of communication by increased noise immunity by compensation of noise signal both during propagation and reading of signal in both wires of the communication line.
