Abstract: The Smith chart is one of the most useful graphical tools for high frequency circuit applications. It provides a clever way to visualize complex functions and solving problems with transmission lines and matching circuits. Here a computer-assisted learning technique is presented using C language for making lively and dynamic problem solving interface, by which one can implement the smith chart and solve problems easily related to transmission line and matching circuit. The concept of explaining the use of an important old tool like the Smith Chart, using modern tool like C to explain the use of the Smith Chart represents a prime example of the melding of the traditional and the leading edge. Here, we have solved some of the most common transmission line problems using this software and have compared the results of both experimental calculations as well as manual calculations
