1. A transmission device comprising:
driver circuitry configured to
transmit a data signal using three or more predetermined number of voltage states, and
set voltages in each of the three or more predetermined number of the voltage states; and
control circuitry configured to control the driver circuitry to perform an emphasis by setting an emphasis voltage that is based on a transition among the three or more predetermined number of the voltage states,
wherein a combination of the data signal using the three or more predetermined number of the voltage states that is transmitted and the emphasis that is performed communicates information to a reception device via a communication network.
