文献[1]提出了无损耗传输线物理模拟的集总等效定理,获得了Π型或T型电路的级联数目与传输线长度、最高频率、延迟时间及其相对误差的解析公式.该文是文献[1]的姊妹篇,通过三个注记,进一步讨论了集总电路的动态响应、特性阻抗精度的提高方法、以及低损耗传输线的物理模拟问题,并给出一些有用的公式和方法,为传输线物理模拟和等效计算的精度控制提供了理论基础.“,”In literature [1], a lumped-circuits equivalent theorem for physical analogy of lossless transmission lines was proposed and the general formulae including chained number, length of transmission lines, the highest frequency, delay time and its relative error were obtained. This paper was a sister of [1] and reported three notes in which dynamic response of the lumped-circuits, improving methods for accuracy of characteristic impedances and physical analogy of lower-loss transmission lines were deeply discussed and some useful formulae and methods were provided as well. The proposed formulae and methods may be used to precision control of physical analogy and equivalent calculation for transmission lines.
