Abstract
PURPOSE:To reject the distortion of pulse by a transmission line, by transmitting data pulse added with a specified pulse and subtracting the added pulse at reception. CONSTITUTION:At a transmission end 1, an offset pulse with a width corresponding to an offset current 5 is outputted after being coupled with the front end of the pulse with a width corresponding to a data current 6 at each channel. In this case, the offset pulse with a width corresponding to the offset current 5 is also outputted. At a reception end 2, a pulse and an offset pulse at each channel are received and the front end of the pulse is cut at an AND gate 8. A subtraction circuit 12 outputs a pulse width subtracting the offset pulse cut at the front end from the pulse of each channel cut at the front end as a data pulse. As a result, the adverse effect due to the distortion of pulse front end generated on the transmission line is eliminated.
