Abstract
A receiving device includes a receiving circuit and an impedance control circuit. The receiving circuit receives a signal transmitted through a communication line. The impedance control circuit is coupled with the receiving circuit and has a detecting part. The detecting part detects a physical value of the signal and the physical value includes at least one of a voltage, an electric current, and an electric power. The impedance control circuit changes an input impedance based on the detected value so that a ringing of the signal is reduced.
