| Zusammenfassung: | To appropriately adjust the susceptibility to noise generation and transmission speed according to the scale of a system.SOLUTION: A control unit 10 generates a rectangular-wave transmission signal. A waveform conversion circuit 40 converts the rectangular-wave transmission signal generated by the control unit 10 into a trapezoidal-wave transmission signal. A waveform switching circuit 50 switches on/off of a waveform conversion operation by the waveform conversion circuit 40. A driving circuit 80 outputs the trapezoidal-wave transmission signal to a communication line when the waveform switching circuit 50 turns on the waveform conversion operation, and outputs the rectangular-wave transmission signal to the communication line when the waveform switching circuit 50 turns off the waveform conversion operation.SELECTED DRAWING: Figure 2
【課題】ノイズの発生しやすさと伝送速度とをシステム規模に応じて適切に調整する。【解決手段】制御部１０は、矩形波の送信信号を生成する。波形変換回路４０は、制御部１０が生成した矩形波の送信信号を台形波の送信信号に変換する。波形切替回路５０は、波形変換回路４０による波形変換動作のオン／オフを切り替える。駆動回路８０は、波形切替回路５０が波形変換動作をオンにしている場合、台形波の送信信号を通信線に出力し、波形切替回路５０が波形変換動作をオフにしている場合、矩形波の送信信号を通信線に出力する。【選択図】図２ |
