差模信号

用改进的滤波器抑制共模、差模信号的传播干扰，设计新型的光耦隔离触发电路以提高电路的整体抗干扰能力。

An improved filter is used to restrain common mode interference and difference mode interference . In order to improve the whole anti-interference of circuit , we also design a new-type mere optoelectronic isolating circuit .

从分析传导测试原理入手，建立了针对差模干扰信号的一阶滤波器的电路等效模型；

By the way of analyzing the transmit test principle , the model of the first-order filter in allusion to DM interface signal are established ;

介绍了抑制干扰的几种主要方法，即差模干扰信号的抑制方法、共模干扰信号的抑制方法、电磁隔离方法等。

It introduces the several methods of controlling interference , i.e. method of controlling differential mode interference signal , method of controlling common mode interference signal and magnetic segregation method .
