摘要： An electromagnetic wave transmission apparatus of the present invention includes a transmission unit whose voltage-current characteristics have a local maximum value and a local minimum value located on a higher voltage side than the local maximum value and which transmits an electromagnetic wave indicating a modulation signal, an acquisition unit which acquires a digital signal, and a modulation unit which modulates the digital signal into the modulation signal which is a signal using voltage values of three levels or more in an oscillation region which is a voltage region that is equal to or more than a voltage of the local maximum voltage and equal to or less than a voltage of the local minimum voltage. The transmission unit preferably transmits a synchronization signal as at least a part of the modulation signal. In this case, the synchronization signal preferably includes a maximum value and a minimum value among the voltage values of three levels or more, and includes a pattern in which the voltage value transitions from one of the maximum value and the minimum value to the other.

摘要： An electromagnetic wave transmission device according to the present invention includes: a transmission unit that has, in voltage-current characteristics, a local maximum value and a local minimum value located on a higher voltage side than the local maximum value and transmits an electromagnetic wave indicating a modulation signal; and a modulation unit which modulates an acquired digital signal to the modulation signal using first voltage values of two or more levels in a first voltage region, which is equal to or greater than a voltage of the local maximum value and is equal to or less than a voltage of the local minimum value, and a second voltage value in a second voltage region, which is less than the voltage of the local maximum value, and a third voltage value in a third voltage region, which is on a higher voltage side than the voltage of the local minimum value. A first signal which transits to any one voltage value of the first voltage values from any voltage value in the first voltage region via the second voltage value and a second signal which transits to the any one voltage value from the any voltage value via the third voltage value are the same signals. The modulation unit selects, out of the first signal and the second signal, the signal having a smaller total transition potential difference.
