This document presents the results of a MATLAB workshop (taller) on Fourier analysis. It includes 4 sections: an introduction describing the objectives of Fourier analysis and the workshop; a development section showing the steps and code to solve 3 problems involving varying the amplitude, frequency, and phase of signals; solving a problem involving harmonic functions; and analyzing an audio signal. Graphs are presented of the signals analyzed. The conclusion emphasizes that practice with tools like MATLAB is important for engineering students to better understand signals and waves.
