Abstract

PURPOSE:To always output the correct reception data by providing a transmitting part including the transmission circuits which output the signals at different transmitting speeds and a receiving part including the reception circuits which input the signals of different transmitting speeds. CONSTITUTION:The transmission data (a) are inputted to three transmission circuits 1 and outputted from these circuits 1 to three transmission lines 6 at different speeds. At a receiving part 5, three reception circuits 3 input the signals of different transmitting speeds. Then a majority deciding circuit 4 compares the output signals of circuits 3 with each other and decides the signal of the highest frequency of equality as a correct signal. Thus only the output signal that is decided to be correct is outputted as the reception data (b). In such a way, the transmitting speed of the signal to be transmitted is changed so that the frequency band of each transmitting signal is changed. Then the influences of noises are reduced and also the occurrence of transmission errors is suppressed. Thus only the correct reception data having no transmission error can be selected and outputted.
