摘要
在传导EMI(电磁干扰)中既存在共模电流也存在差模电流,要很好的分析传导EMI系统,就很有必要对共模干扰信号和差模干扰信号分离开来单独进行测试。这样,共模和差模噪声的分离就显得很重要了。
There are some differential-mode(DM) and common-mode(CM) noise in conducted EMI (electromagnetic interference) system,it is very important to measure the DM and CM separately in order to analyze the conducted EMl.usefully. It is important to separate the DM and CM noise.
