Likewise, this&nbsp;</p> <p>interface was implemented using various components such as Drop Down, Button, <br>Knob, Axes, among others, which allowed the choice of the number of sinusoidal <br>components used in the decomposition, as well as the choice of the type of signal, <br>its amplitude, frequency, DC level and duration time of the same. Therefore, this <br>implementation complements the teaching-learning process developed remotely <br>for a topic in the Telecommunications I course of the 6th academic semester of the <br>Electronic Engineering Degree at Ricardo Palma University. Finally, the graphical <br>results are presented for the case of four choices of periodic signals, with different <br>amplitudes, frequencies and DC levels; as well as the numerical results in terms of <br>the mean square error, showing a lower value for the triangular signal despite using <br>a reduced number of sinusoidal components</p>}, number={23}, journal={Scientia}, author={HUAMANÍ NAVARRETE, Pedro}, year={2023}, month={ene.}, pages={199–213} }
