Document Summary
Wave equations / finding wave impedance of the. The phasor voltage and current equations at the generator side are. The input impedance at the source end of the line is given by finding the value of or as. Equating the two input phasor voltage equations and solving for. Using the voltage divider rule we can write the phasor voltage at the input of the source end as. Knowing the input impedance at the source end is important in. Lecture notes page 1 gives us the number of uknowns in the general solutions to only two voltage amplitudes as shown below. Note: by determining that we were able to reduce amplitudes were related using the reflection coefficient . The reduce the number of uknowns to just one . Finally by applying the boundary condition at the source the value for does not replace the transmission line instead replaces the transmission line and the load impedance.
