数字通信设备系统的“ＥＭＣ”点滴谢锋在传输过程中，数字通信信号抗外界电磁场干扰性能优于模拟信号，这是人所共知的事实。但它不等于不受外界电磁场的干扰影响，比如，雷电冲击波、电火花脉冲等的干扰影响时有发生，轻则误码，重则烧毁设备。下面列举二例加以说明：某... Digital communications equipment system “EMC” bit by bit In the transmission process, the digital communication signal against external electromagnetic field interference performance is better than the analog signal, it is well known fact. However, it does not mean that it is not affected by the interference of external electromagnetic fields. For example, the influence of lightning impulses and spark impulses may sometimes occur, ranging from error codes to heavy equipment burned. Here are two examples to illustrate: a ...
