We propose two experiments suited for high school and/or undergraduate physics laboratory which are aimed at the discovery of the practical meaning and utility of the FFT analysis as a mathematical and graphical instrument. They intend to discriminate different periodic signals in various situations, ranging from basic, demonstrative measurements to very complex, real-research experiments. In our proposal, inexpensive digital instruments can be used, with surprisingly accurate results.

They intend to discriminate different periodic signals in various situations, ranging from basic, demonstrative measurements to very complex, real-research experiments.
