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 section12solves a differential equation regarding electromagnetic interaction of each line segment based on the predetermined distributed parameters, including a distributed self-inductance Li, a distributed resistance Ri, and a distributed capacitance ciand a distributed conductance giin relation to a reference potential plane in the transmission line, and a distributed mutual inductance Mij, a distributed capacitance Cij, and a distributed conductance Gijbetween the transmission line and another transmission line, which are input from an input section11, and calculates the characteristic data of the transmission line.
