タ伝送装置。 A transmitting clock that outputs a clock signal of a predetermined frequency to a transmitter, a data addition circuit that adds data different from the bit data transmitted earlier to the middle of multiple bits of transmitted data expressed in binary values; a data transmitting circuit that transmits multiple bits of data added by this circuit as an NRZ signal in synchronization with the clock signal; a receiving clock that outputs a clock signal of a predetermined frequency to a receiver; a data receiving circuit that receives the transmitted data in synchronization with a signal, and a level change detection that detects a change in signal level at least at the boundary between data added by the data adding circuit and data received earlier than this data. A receiving clock reset circuit that resets the receiving clock based on a detection signal of this circuit, and an additional data erasing circuit that erases the additional data from received data. Device.
