Abstract: PURPOSE:To suppress satisfactorily the noise effect and to attain the transmission of data with high reliability by transmitting the clock as it is with the data transmitted with a sum operation carried out with the clock and reproducing the data at the reception side with a difference operation carried out with the clock. CONSTITUTION:The waveform of a clock CKP has an amplitude set within a range between -V1 and 0; while the waveform amplitude of the data TXD is set within a range between -V1 and +V1. A waveform shown by NRZ is obtained by calculating (TXD-CKP), and the reception data PXD is obtained by latching it at a negative edge of the clock. While (TXD-CKP) is carried out by a differential amplifier 20 at the side of a receiving station 2. Then a waveform shaping circuit 21 performs the waveform shaping. The data TXD is supplied to a D type flip-flop 23 together with the clock CKP that has the positive polarity through a DC reproduction circuit 22. THen the data RXD is delivered. Thus the noises applied usually in common to both a clock line 4 and a data line 3 from an external noise source are all eliminated substantially. In such a way, the effect of noise is reduced considerably.
