| Abstract: | The research in this paper is based on the theory of transmission line,Firstly,the measurement principle of characteristic impedance based on Time Domain Reflectometry is introduced briefly.What is more important,the implementation of signal process in the TDR is described in details.And by two development tools of CCS and Matlab,the data from the practical measurement by TDR is used for simulation and proof.By comparing the two results,the paper comes to the conclusion that the measurement method is correc... |
