How to use the FFT on a signal of any size

[@ezzoalgaddafy5934]

I started watching your videos while i was preparing my graduation project on ofdm systems ,i was fascinated by fourier transform and fft and you helped me to intuitively understand fft ,now am doing masters degree on communications engineering as fft gave passion to study

Thank you! Cheers!

Great video. Can you talk about bluestein fft algorithm? It also works with arbitrary sizes. What does it do to the signal?

I need to research this as I am not as familiar with it as I am with the Cooley-Tukey FFT. However, here is a summary of some stuff pulled from various sources on the internet. docs.google.com/document/d/1CWRSVV6eT6kKvjHsGTA3TUBORF9s-fcxJMPBsry0dGY/edit?usp=sharing
