But most attention should be put on the PCB design, elements position and line connection, which can suppress the source of the common mode disturbance.
但最根本的应该是在印刷电路板设计、元器件布置和连接线的安排上下功夫,抑制共模骚扰源的产生。

The problem in the communication between DSP and PC based on RS-485 is presented, and the solution ofcommon-mode disturbance and EMI which are generated by incorrect ground connection is stated.
This paper deals with a comprehensive and detailed introduction about the classification, cause, behavior and suppression methods of the common mode disturbance combining theory with examples.
