<p>A communication system includes a wired communication device (14) and a communication device (2) that can communicate with a wireless communication device and the wired communication device. The communication device (2) includes a clock output unit (46) and a modulator (47). The wired communication device (14) includes a clock extracting unit (52), a signal extracting unit (53), and a processing unit (54). The communication device and the wired communication device are connected to each other by a first connecting line through which a modulated signal is sent from the communication device to the wired communication device, and a second connecting line, which is different from the first connecting line, through which a signal is sent from the wired communication device to the communication device.</p> |
