多信道信号传输系统的电磁兼容性设计

EMC Design in a Multi-channel Transmission System

在电磁兼容性设计过程中，整机机箱、部件壳体及组件围框的设计是减少电磁干扰降低设备对电磁干扰的灵敏度的关键措施之一。本文就是根据多信道信号传输系统的特点，分析了系统可能出现的问题，进而提出了如何通过改进设计，减少系统内各整机部件之间的电磁干扰，提高设备的电磁兼容性能，保证系统正常工作的问题。

In the process of the design of electrical/magnetic compatibility, the design ofcabinets and shielded enclosures in critical to the reduction of equipment sensitivityto electrical and/or magnetic interferences. This paper, considering the nature ofmulti-channel transmission system, present and analysis of all problems that thesystem may occur and therefore put forth the solutions to the reduction of EM in-terferences between subassemblies so as to improve EMC performance and securesystem normal operation.
