了解共模信号

资料介绍
摘要:要了解如何创建,然后抑制共模信号,你首先应该了解在普通电缆配置盾牌和理由的互动。下面的讨论中定义了一个共模信号,回顾了常见的电缆配置,考虑屏蔽与非屏蔽电缆,并介绍了典型的接地措施。文章论述了创建和拒绝,使共模信号的方法。

Understanding Common-Mode Signals

Abstract: To understand how common-mode signals are created and then suppressed, you should first
understand the interaction of shields and grounds in common cable configurations. The following discussion
defines a common-mode signal, reviews the common cable configurations, considers shielded vs. unshielded
cables, and describes typical grounding practices. The article discusses methods whereby common-mode
signals are created and rejected.
