PROBLEM TO BE SOLVED: To easily attain communication at a high transmission rate. SOLUTION: Transmission lines between a transmitter 11 and a receiver 12 are a data signal line 13 through which serial data are transmitted and a delimiter signal line 14 through which a delimiter signal to allow the receiver side to recognize delimiters of bits is transmitted in the case that consecutive bits are identical in the transmitted serial data as shown in figure (a). When logical values of consecutive bits of the transmission data are changed, the level of delimiter signals is unchanged as shown is figure (b). When consecutive buts of the transmission data are identical, the level of the delimiter signals is changed. The receiver side receives the data signals and the delimiter signals and discriminates a point of time when either the level of the data signal or the delimiter signal is changed to be a delimiter of bits and reads the digital data by discriminating the logic level of each bit of the data signals. |
