Motivation
The
weapon of choice for many engineers is the graphing calculator. The
graphing calculator not only gives representations of functions but it
also can be used to find intersections, minimums, and maximums of these
same functions. The advantage of the calculator is that it does all
these things with relative ease. The Smith Chart is the graphing
calculator for transmission lines. When used regularly one can find
many parameters of the transmission lines with relative ease.
Relationship to Project
One way to read the output of transmission
line circuits is to use the Smith Chart. When you read the
output using a Smith Chart, you can identify the inductive and
capacitive regions. You can also use a Smith Chart to quickly
predict what the possible output would be if you were given
transmission line equations.
Goals
Be able to distinguish inductive and
capacitive regions of Smith Chart
Be able to identify different scales of
the Smith Chart
Be able to use the Smith in order
to get transmission line parameters
Be able to calculate a normalized load
impedance given the a SWR calculated from the Smith Chart
