Abstract
The invention is aimed to analyze the characteristics of a transmission line only by inputting the specific distributed parameters without mesh dividing the transmission line to be analyzed into minimal unit required for the analysis. An arithmetic operation sectionsolves a differential equation regarding electromagnetic interaction of each line segment based on the predetermined distributed parameters, including a distributed self-inductance L, a distributed resistance R, and a distributed capacitance cand a distributed conductance gin relation to a reference potential plane in the transmission line, and a distributed mutual inductance M, a distributed capacitance C, and a distributed conductance Gbetween the transmission line and another transmission line, which are input from an input section, and calculates the characteristic data of the transmission line.
