We propose two experiments suited for high school and/or undergraduatephysics laboratory which are aimed to the discovery of the practical meaningand usefulness of the FFT analysis as a mathematical and graphical instrument,intended to discriminate different periodic signals in various situations,ranging from basic, demonstrative measurements to very complex, real-researchexperiments. In our proposal, quite inexpensive digital instruments can beused, yet with accurate out-of-the-box results.
