PURPOSE:To correct a receiving waveform, by distorting a waveform of a transmission side into a shape in advance such as a differentiated waveform, and transmitting the result. CONSTITUTION:Transistors 1, 3, inverter 2, and a pulse transformer 4 constitute a driving circuit. A series circuit comprising a capacitor 6 and a resistor 7 is connected between an intermediate tap (b) of the secondary winding of the transformer 4 and one end (d) and an output pulse is extracted from a connecting point (a) and the other end (c) of the secondary winding. Since a differentiating circuit comprising the resistor 6 and the capacitor 7 is connected to the output side of the transformer 4, the waveform distortion due to an earth capacity in case of a long range transmission is improved. |
