A method of cancelling noise present in a data signal received on an electrical bifilar line, is implemented by a sender-receiver device comprising a first transformer, termed the differential mode circuit, the primary side of the first transformer connected by two wires to the bifilar line, a second transformer, termed the common mode circuit, the primary side of the second transformer connected to the primary side of the differential mode circuit, and to ground. The method comprises during an adjustment phase: obtaining a first voltage value on the bifilar line, termed the differential mode voltage; obtaining a second voltage value at the common mode circuit, termed the image voltage, resulting from the differential mode voltage; calculating the ratio between the second and first voltage values, termed the conversion ratio. The method comprising during a cancellation phase, subsequent to the adjustment phase; receiving the data signal and simultaneously obtaining a third value corresponding to the image voltage; cancelling the noise in the data signal, by subtracting an estimation of the noise, calculated by dividing the third value by the conversion ratio.
