An undershoot eliminating circuit is provided between a pulse transformer of a pulse transmitter coupled to a transmission line and a pulse transformer driving circuit for driving the pulse transformer. The pulse transformer driving circuit has an impedance high enough to cause the pulse transmitter to be substantially isolated from the transmission line. The undershoot eliminating circuit includes a capacitor, and a switching unit. The switching unit is connected to the capacitor, and has the function of selectively connecting the capacitor to the pulse transformer driving circuit and the pulse transformer in parallel on the basis of a voltage based on a pulse wave generated by the pulse transformer driving circuit and applied across the switching unit.
