电磁兼容技术在智能语音录放系统设计中的应用

Application of Electromagnetic Compatibility Technology into Design of Intelligent Language Recording System

随着电子技术的飞速发展,高密度、高频率的电子产品迅猛增长,电磁兼容问题日益严重,EMC设计技术和方法已经成为重要的设计内容。阐述了电磁兼容技术的发展、电磁兼容的基本概念以及电磁干扰的产生机理,并以一款智能语音录放系统的EMC设计为例,对如何完成满足电磁兼容要求的产品给出了建议。

Along with the rapid development of electronic technology, high-density and high-fre- quency electronic products have witnessed a quick rise, and electromagnetic compatibility （EMC） has become ever-increasingly important, the technology and method of EMC design have become an integral part of designing. This paper clarifies the development and basic concepts of EMC technology, and the mechanism that results in electromagnetic interference. Taking the EMC de- sign of an intelligent language recording system as an example, this paper proceeds to put forward suggestions on how to complete products that satisfy EMC requirements.
