This article describes the procedure for the implementation of a graphical user
interface using the App Designer development environment of the Matlab software
and its Toolbox Signal Processing and Symbolic Math, which allowed obtaining
the Fourier Series coefficients for seven periodic signals followed by a graphical
representation in the domain of time and frequency through pulses. Likewise, this
interface was implemented using various components such as Drop Down, Button,
Knob, Axes, among others, which allowed the choice of the number of sinusoidal
components used in the decomposition, as well as the choice of the type of signal,
its amplitude, frequency, DC level and duration time of the same. Therefore, this
implementation complements the teaching-learning process developed remotely
for a topic in the Telecommunications I course of the 6th academic semester of the
Electronic Engineering Degree at Ricardo Palma University. Finally, the graphical
results are presented for the case of four choices of periodic signals, with different
amplitudes, frequencies and DC levels; as well as the numerical results in terms of
the mean square error, showing a lower value for the triangular signal despite using
a reduced number of sinusoidal components
