摘　　要：电磁干扰(EMI)可分为传导干扰和辐射干扰,消除干扰的方法可以采用硬件方法和软件方法,硬件方法主要有屏蔽、接地、隔离和滤波等,而软件方法主要是滤波。笔者对各种方法进行总结,并指出各种方法所存在的问题以及适用场合,并对一些常用方法提出改进措施。Electro magnetic interference (EMI) can be classified into conductive interference and radiant interference. The interference can be eliminated by hardware or software. The hardware for elimination consists of shield, grounding, isolation, filter, etc; and the software is mainly by filtering. These methods are discussed, including their applications, existing problems and some suggestions for improvement.
