The present work deals with a study of the Discrete Fourier Transform, being one of the most popular techniques to analyze digital signal processing systems applied in analyzing digital signals. Furthermore, it is an important computational tool to recover the frequency distribution of a sampled signal, using some mathematical and graphical techniques to reconstruct discrete signals. The methodology used is theoretical-practical applied to the concepts of the discrete Fourier transform, executing an algorithm through a numerical simulator. Therefore, three examples of different applications allow us to conclude with the importance of implementing the discrete Fourier transform in the analysis of digital signals.
