电和磁是互相关联的。每一台电子设备都不可避免电磁兼容问题。因此,为了使电子设备可靠运行,必须研究电磁兼容技术。以实例说明了电磁兼容的思路和设计方法。通过对电磁干扰源的明确认识,对电磁干扰引入路径的清楚了解,针对电磁干扰敏感的接收电路进行重点保护。
Electricity and magnetism are interrelated. Every electronic device is inevitable electromagnetic compatibility issues. Therefore, in order to make reliable operation of electronic equipment, electromagnetic compatibility technology must be studied. An example is given to illustrate the idea of electromagnetic compatibility and design method. Through a clear understanding of the sources of electromagnetic interference, a clear understanding of the path of introduction of electromagnetic interference and a focus on protection against electromagnetic interference-sensitive receiving circuits are provided.
