【摘要】 将分布参数方块结构图理论用于处理高速传输线问题,给出了一种传输线分析的解析方法．将分布参数的传输线视为一个“方块”,给出其传递函数后．利用过渡方块将传输线与集中参数元件或其他分布参数元件相连,计算出整个系统的传递函数．除由数字采样引起的误差外,该方法是精确的,且在整个处理过程中不改变传输线分布参数元件的性质,不存在电路稳定性的问题．最后给出了算例,并将计算结果与Hspice模拟结果进行了比较．更多还原

【Abstract】 It applies the theory of block structures of distributed parameter systems for analyzing of high-speed transmission lines. An analytic analysis method for transmission lines is presented. The transfer function is computed for transmission lines, and then the transfer function of the whole systems made up of transmission lines and other elements that are interconnected by transition blocks can be obtained. The proposed method is exact and the only error is brought by sampling. The method does not change the quality of transmission lines, so the stability of the circuits need not be considered. Examples are presented and the results are compared with those computed by Hspice.更多还原
