Abstract
A signal receiver includes: a receiving circuit that receives a differential signal via a transmission line, which includes a pair of signal wires for transmitting the differential signal; and an impedance control circuit that controls an input impedance so as to reduce a common mode noise. The impedance control circuit includes a detection element for detecting at least one of a voltage, a current and an electric power of the common mode noise. The impedance control circuit controls the input impedance in accordance with change of the at least one of the voltages the current and the electric power of the common mode noise.
