Intuitive Guide to Fourier Analysis by Charan Langton and Victor Levin

I am working on a book with the imaginative and creative title of “Intuitive Guide to Fourier Analysis”. This is an old topic, but forever confounding in all its myriad forms. The book will have some of my DFT, FFT

Fourier Made easy part 2 – new version uploaded

I have uploaded a new version of the Fourier Made Easy part 2 tutorial. In this version, I have included more examples as well as Matlab code to plot some of the key pictures.  I get requests to include code,

Video that explains the complex exponential

While writing the second part of the Fourier tutorial, I came across this video which does a great job of explaining the complex exponential, its relationship to sinusoids and hence to the reason why signal processing math is done with

Fourier tutorial part 1 – updated

I am going through my old material and am updating it. I have just uploaded FFT Part 1 after changing it in many places. If you have comments on this tutorial (any including typos!), please post them here. Charan
