Research on Transient Process of Uniform Transmission Line

摘要

In this paper, the circuit model and equation of uniform transmission line are analyzed theoretically. Because the equation of transmission line is a first-order differential equation, it is hard to carry on research on the transient process of transmission line in theory, In order to observe the reflection phenomenon and transmission delay phenomenon, the experimental device is set up in laboratory. Digital oscilloscope is used to capture the phenomenon of reflection and transmission delay. Different transient process is obtained by changing the material, distribution pattern of transmission line and signal frequency, the factors affecting the traveling wave of transmission line is obtained, which provide reliance of theory research of uniform transmission line.
