信号长线传输的干扰与抗干扰

Disturbance and Anti-disturbance of Transmitting Signal through Long line

分析了电信号在长线传输中电压反射引起电信号畸变的原因，叙述了电信号在长线传输中电磁场干扰的耦合途径，给出了相应的抗干扰措施。

This paper analyses the reasons for electrical signal distortion brought by voltage reflection when transmitting through long line.T he electromagnetic interference linking pathways are described.The corresponding an ti-disturbance methods are also presented.
