Nowadays,the development of science and technology is becoming more and more powerful,and the application of transmission line is popularized.This paper introduces and studies the basic transmission line theory,expounds the transmission line theory from Kirchhoff’s law,and deduces the transmission line equation.In the process of analyzing the transmission line emission,the impedance characteristics of the transmission line are obtained,and the signal integrity is ensured by setting the impedance matching network to offset the transmission line,and the occurrence of the ringing and return ditch phenomenon brought by the reflection of the transmission line as low as possible.Finally,the application of transmission lines is described to highlight the important role of transmission lines in signal transmission.
