Claim:
1. A data transmission system, comprising: a transmitting device configured to transmit a data signal; a receiving device configured to receive the data signal transmitted from the transmitting device; and a transmission path for transmitting the data signal from the transmitting device to the receiving device, the receiving device comprising: the switching unit is configured to select a first resistor of the plurality of resistors, the first resistor having a higher resistance value than a characteristic impedance of the transmission path, during a first period, which is a predetermined period from a time point at which the polarity is inverted, and to select a second resistor of the plurality of resistors, the second resistor having the same resistance value as the characteristic impedance, during a second period, which is a period from an end point of the first period until the polarity is inverted next.
