1. A transmission device comprising:
a driver circuit configured to transmit a data signal using a first voltage state, a second voltage state, and a third voltage state interposed between the first voltage state and the second voltage state, a voltage of the third voltage state being changeable; and
a controller configured to change the voltage in the third voltage state to cause the driver circuit to perform emphasis, wherein
the controller determines whether to cause the driver circuit to perform emphasis in accordance with at least one change among the first voltage state, the second voltage state, and the third voltage state,
the data signal indicates a sequence of symbols, and
the controller changes the voltage in the third voltage state on a basis of a transition of the symbols in the sequence.
