An experimental simulation lab in MathCAD for teaching signal processing

MathCAD is a powerful tool in the engineering field to analyze complex systems through the computation of the corresponding mathematical models. The experience obtained from the use of MathCAD as a complementary laboratory for teaching signal processing in both cases, continuous and discrete, is presented. A collection of different cases-of-study in the area of signal processing such as Nyquist criteria, digital filtering in the time domain by difference equations, relation to frequency response in both continuous and discrete domains, modulation, and other examples is presented. Their use in the classroom to support experimental work in the electrical engineering curricula at the batchelor level in Universidad de las Americas during several semesters is discussed
