摘　　要：EHC(Electro Hagnetic Compatibility)是指干扰可以在不损害信息的前提下与有用信号共存。随着数字化产品的不断问世,其电磁兼容性的设计越来越引起人们的重视,因为高速数字电路工作时,会产生大量的高频干扰信号,处理不好,不仅影响电路本身性能,而且还会影响周围环境。所以如何减少数字电路部分的电磁干扰,使其能够安全有效的工作,越来越引起人们的重视。该文主要对数字电路中的常见干扰进行分析,并对数字电路中如何降低干扰的技术进行了详细的讨论。The Electro Magnetic Compatibility is that disturbance can coexist with useful signal on the premise that information isn＇t damaged. With the digital productions comes out,the design of electromagnetism compatibility receives people＇ s attention.when high-speed figure circuit working, much of high freguency disturbance signals will be produced and will affect the circuit and the environment, if the signals cannot be dealed Well.How to cut down the electromagnetism disturbance of digital circuit and make it work efficiently had already receive people＇s attention.ln this paper,the common disturbonce of digital circuit is discussed and how to cut down the disturbance of digital circuit is already discussed.
