几年前,当普遍使用无线电频率干扰这个术语时,电磁干扰仅限于通讯设备方面(如收音机、电话、雷达等)。屏蔽的早期应用主要是在射频电路中隔断不必要的噪声。今天,在计算机、微处理机和外部设备中,对数字和模拟
A few years ago, when the term radio frequency interference was commonly used, electromagnetic interference was limited to communications equipment (such as radios, telephones, radars, etc.). Early shielding applications mainly in the radio frequency circuit to cut off unnecessary noise. Today, in computers, microprocessors and external devices, numbers and simulations
