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.
