Continue your education of the Fourier transform with my latest video that explains how the numbers output by a DFT relate to all those waves (harmonics) you see in graphical demos.
I also introduce you to another French guy, called Charles Hermite (pronounced ‘Sharl Air-Meat’), and explain the symmetries and parallel processing inherent in the maths of the FT
