Abstract
Examples of the concept of explaining the use of an old tool like the Smith chart using modern tools like MATLABTM
[1] in combination with e-learning facilities are illustrated by MATLAB scripts. These display the step-by-step graphical
procedure that must be used to solve single-stub impedance-matching problems, and they illustrate the variation of the
corresponding bandwidth. These scripts are important for students, since they teach them how to solve several kinds of
transmission-line problems by themselves, with a paper chart using a pencil, a ruler, and a compass.
