PROBLEM TO BE SOLVED: To provide a data reception device in a data communication system, which can precisely identify a transmission signal from a transmission signal and a human body signal, whose levels fluctuate owing to environment, an individual difference and time. SOLUTION: A data transmission device 1 executing amplitude modulation or modulation where a pulse is set to be a carrier based on data to be transmitted and outputting a modulation signal from a part fitted to a human body and a data reception device 2 receiving the modulation signal outputted from the data transmission device 1 by bringing the human body 3 on whom the data transmission/reception device 1 is fitted into contact with the device 2 and demodulating the modulation signal are included in a data communication system. The data reception device 2 has a signal characteristic emphasis part emphasizing a difference between the modulation signal and a human body signal added to the modulation signal in transmitting data. |
