Transmission coefficient of traveling wave The transmission coefficient of traveling wave can be expressed by the ratio of transmitted voltage (current) wave to incident voltage (current) wave. Set the wave impedance of the two sections of the line, respectively, the transmission coefficient of the traveling wave. The transmission coefficient of the traveling wave can be expressed by the ratio of the transmitted voltage (current) wave to the incident voltage (current) wave. The transmission coefficients of the voltage traveling wave and the current traveling wave are the same, so the description no longer distinguish. When the wave impedances of the two lines are Z1 and Z2 respectively, then the transmission coefficient: It can be deduced that the relationship between the transmission coefficient and the voltage reflection coefficient is: 1+ρu=-γIn practice, many of the situations encountered are transmission phenomena when there is a low resistance fault in the middle of the cable as shown in Figure 2.8.
At this time, the transmission coefficient is obtained: as mentioned above, where K=Rf/Z0. 1111MicrosoftInternetExplorer402DocumentNotSpecified7.8 poundsNormal0.
