摘要 分析了以计算机为核心的信息技术设备的电磁辐射机理,模拟出了矩型脉冲信号的差模辐射频谱和三角脉冲信号的共模辐射频谱。测试了PⅢ800计算机主机及显示器的电磁发射电场强度,并对结果进行了分析。 The mechanism analysis of EM radiation about digital ITE such as computer, is given, and the simulation results of the differential-mode radiation about the rectangular pulse and the common-mode radiation about the tripulse in digital circuit are shown. Then, the radiation emission of PⅢ800 and displayer are measured and analyzed.
