| 摘 要： | 随着高速PCB板上信号传输速度的不断增加,有损传输线的暂态分析的重要性与日俱增。本文首先将传输线数学模型-电报方程离-散化为高阶常微分方程组,在满足稳定性条件下正确选择时间、空间步长,利用微分方程数值解法编程求解。该方法具有精度高计算时间少的优点。

| Abstract: | Transient response analysis of transmission line has recently been received more attention because operating speeds in high - speed PCB are increasing. This paper first transfers the mathematical mode - Telegraph equations- to high order ODE, then chooses time and space pace on the premise of guaranteeing stable conditions, finally uses numerical solution to program and compute. This method has advantages of high accuracy and less computing - time consumption. |

| Keywords: | high- speed PCB board numberical solution for ODE transient response of transmission line |
