在当今电子信息设备飞速发展的时代,人们对信息高速化和宽带化的要求也日益增强,使得数字电路的设计应运而生。然后大量的电路在一个狭小的电路板使用,电路中的一个简单的噪声都会影响到电路的使用。如何能够通过简单的布线或者排线方法降低或者解决数字电路当中出现的噪声,成为电路设计师的研究重点。电磁干扰是指当电子或电气设备内部或外部的电磁能量使设备产生了不希望的响应,如性能降级或误操作。可通过传导、祸合、辐射三种途径由干扰源向外传播或进入敏感设备。电磁兼容则是指不损失
In today’s era of rapid development of electronic information devices, people are also experiencing increasing demands for speeding up and broadbanding of information, and the design of digital circuits has come into being. Then a large number of circuits in a small circuit board to use, a simple circuit noise will affect the use of the circuit. How to reduce or solve the noise appearing in digital circuits through simple wiring or cable laying becomes the research focus of circuit designers. Electromagnetic interference refers to the device when the electromagnetic energy inside or outside the electronic or electrical equipment to produce an undesirable response, such as performance degradation or misuse. It can be transmitted by sources of interference or into sensitive equipment through three ways of conduction, combating and radiation. Electromagnetic compatibility means no loss
