An example
A 50-? lossless line is terminated in a load ZL
(25j50)?. Use the smith chart to find a) voltage
reflection coefficient, b) the voltage
standing-wave ratio, c) the distances of the
first voltage maximum and first voltage minimum
from the load, d) the input impedance of the
line, given the line is 3.3?, and e) the input
admittance of the line.
