摘要
随着电子技术的发展,电子产品广泛应用,改善了人们的生活。然而各种电子产品在使用时由于需要使用电源,需要进行各种解码,因此必定会产生各式各样电磁干扰。要使得本机能正常工作,必须在设计之初就充分考虑到产品的电磁抗干扰的问题。通过对DVBT机顶盒电磁抗干扰现象的具体分析,有针对性地通过改进电路设计、增强接地和屏蔽措施,修改PCB LAYOUT,有效地提升系统对电磁干扰的承受能力,达到所销往目的国的电磁抗干扰标准要求。
In order to make the electronic products work properly, the electromagnetic interference problem must be con- sidered in the initial design. The specific analysis on the electromagnetic interference of DVBT STB was conducted. The productls capacity of anti-electromagnetic interference was effectively improved by modifying the circuit design, grounding and shielding measures, and PCB layout. The quality of the product has reached the international electromagnetic compatibility standards of the selling markets in destinations.
