近年来随着科学技术的迅速发展,新型电子元器件不断出现,从电子管、半导体、集成电路到大规模集成电路,从模拟信号到数字信号,从简单的电子玩具到复杂的仪表控制装置。大型计算机和控制装置,使用的电磁环境愈来愈复杂。电磁兼容是一门新兴的综合性学科,主要研究电磁干扰和抗干扰问题,即怎样使在同一电磁环境下工作的各种电子电气设
In recent years, with the rapid development of science and technology, new types of electronic components are emerging, from electron tubes, semiconductors, integrated circuits to large scale integrated circuits, from analog signals to digital signals, from simple electronic toys to sophisticated instrument control devices. Large computers and control devices, the use of electromagnetic environment more and more complex. Electromagnetic compatibility is an emerging comprehensive discipline, mainly on electromagnetic interference and anti-interference problems, that is, how to make all kinds of electronic and electrical work in the same electromagnetic environment
