辐射电磁干扰
采用双绞线传输可以有效减少高速率长距离传输数字信号时常见的辐射电磁干扰(radiated EMI)和接收电磁干扰(received EMI)。RS-485与RS-422一样,其最大传输距离约为1219米,最大传输速率为10Mb/s。
辐射性EMI
无论是传导性EMI (Conducted EMI)还是辐射性EMI(radiated EMI)均有差 模 无论是传导性EMI EMI)还是辐射性 还是辐射性EMI(radiated EMI)均有差 (differential mode noise)和共模(common mode n...
它不仅能衰减沿电源线传导的EMI能量,同时也对EMI的辐射有显著的抑制作用。
Basing on dominant effect theory in EMC, conducted emi and radiated emissions of twisted-pair wires are mostly respectively due to differential-mode currents and common-mode currents.本文根据电磁兼容优势效应理论,推导出双绞线传导干扰主要由差模电流引起,辐射干扰主要由共模电流引起。
