Exploring The FFT - GF4 As an Educational Tool (Part 1)

GF4 can be used as an educational tool to explore various corners of data analysis. In this post, we will look at some properties of the Fast Fourier Transform, or FFT. The FFT is a commonly used way to decompose a signal into its frequency components. If you are already familiar with the FFT, none of this will be new, but it may still be interesting to see the various properties materialize before your eyes. If you do not know much about FFTs, it may be interesting and educational. In any case, this post shows the use of some of GF4’s capabilities and commands.
