    摘要: A driving circuit for transmission lines. The driving circuit transforms outgoing signals of an internal circuit to signals large enough to be sent to an external circuit by the transmission lines, especially for RS-232 transmission lines. It comprises three transistors, six resistors, three capacitors and one diode. The expensive signal driver chip needed in the conventional circuit is not necessary in the present invention. The expensive chip is replaced by cheap discrete components. This reduces the cost of the driving circuit.
