Vol. 52, N.º 2 (2010), pp.145-150.1045-9243http://hdl.handle.net/10400.21/521The concept of explaining the use of an old tool like the Smith chart, using modern tools like MATLAB [1] scripts in combination with e-learning facilities, is exemplified by two MATLAB scripts. These display, step by step, the graphical procedure that must be used to solve the double-stub impedance-matching problem. These two scripts correspond to two different possible ways to analyze this matching problem, and they are important for students to learn by themselves.engSmith chartImpedance matchingStub impedance matchingTransmission lines theoryMatlabjournal article10.1109/MAP.2010.55256011558-4143
