| 摘 要： | 在通信系统中,引起误码率提高的一个重要原因是系统中同轴连接器的电接触故障.以前的研究表明,接触故障对信号传输的影响与很多因素有关,如接触阻抗和信号传输频率.文中基于这些研究结果,利用计算机仿真对频率这一影响因素做了进一步研究.研究证明,电接触故障对信号传输的影响与信号传输频率有关,而且在不同情况下频率的影响程度是不同的.

| Abstract: | It is found that electric contact failure of coaxial connector is one of the most important factors causing high error code rates in communication systems. In former research the effects of electric contact on signal transmission have relations with a lot of factors, such as contact impedance and the frequency of transmission signal. Basing on these researches, one of the influence factors, the frequency of signal transmission, is studied in this paper by computer simulation. Results show the effects of electric contact on signal transmission have relations with the frequency of signal transmission, and the degree of influence alters in different situation. |
