屏蔽与接地技术中值得注意的几个问题

Several Notable Problems of the Technology about "Shielding and Grounding

屏蔽线信号传输线路被广泛应用在计算机网络系统和有线电视系统中，它既可以防止被干扰，也可以防止对外辐射造成干扰。本文通过对几种不同的’‘屏蔽接地”形式的比较，说明干扰电压的形成及其解决方法。

The signal transporting circuit shielded is widely applid in computer network system and cable TV system. It can not only precent to be interfered,but also precent radiation out to cause interference. This essay explains the cause of interference voltage and the solution to it by the comparision with a various pattern of 'shielding & grounding'.
