PROBLEM TO BE SOLVED: To compensate a signal depending on transmission characteristics of a printed circuit board.SOLUTION: A control device 101 is an electronic component connected on a printed circuit board 100. On the printed circuit board 100, a closed circuit conducting wire for causing a signal input from the control device 101 to be fed back to the control device 101 is wired. The control device 101 inputs a signal to the closed circuit conducting wire and acquires the signal fed back from the closed circuit conducting wire. Subsequently, the control device 101 identifies transmission characteristics of the conducting wire wired on the printed circuit board 100 based on a waveform of the signal input to the closed circuit conducting wire and a waveform of the signal acquired from the closed circuit conducting wire. Then, the control device 101 sets based on the identified transmission characteristics, amplitude and a compensation value of a signal to transmit through the conducting wire wired on the printed circuit board 100. |
