This Notebook introduces frequency analysis, including Discrete Fourier Transforms (DFTs) and the intuition for how they work, Fast Fourier Transforms and spectral frequency plots, and Short-time Fourier Transforms (STFTs) and spectrograms.
You can view the Notebook in html here but we also strongly recommend working with our Notebooks locally by performing a git clone on https://github.com/makeabilitylab/signals.git and running the Jupyter Notebook on your system (see installation notes).
