On an interface between LSIs, boards, devices (units), and others, the data transfer efficiency per signal line is improved. A shift circuit 710-0 shifts a piece of digital signal D1(0) for output as three digital signals D1S(00) to (02). An analog conversion circuit 720-0 converts the three digital signals D1S(00) to (02) into a piece of analog signal A2(0) for transfer. A digital conversion circuit 730-0 converts the piece of analog signal A2(0) into three digital signals D3(00) to (02). A selection circuit 740-0 makes a sequential selection from the three digital signals D3(00) to (02) to output a piece of digital signal D4(0). |
