The Fast Fourier Transform (FFT) is a powerful tool for analyzing signals in the frequency domain. Python and SciPy provide an easy way to perform FFTs. To use SciPy, the following code can be used: ...

Purpose for this tutorial is to show in a visual way how a Fourier transform works and can be applied on a real use-case.
