Discrete Fourier Transform - Example

We do a very simple example of a Discrete Fourier Transform by hand, just to get a feel for it. We quickly realize that using a computer for this is a good idea...

Thank you. Precise and to the point. To me this was the best explanation on the whole Internet (after two days of search), and of course much better then any of my professors.

This is a great explanation, this all makes so much more sense to me now. Can you explain how you find delta x?

Thank you for your video. It was the best explanation of DFT I have seen.

I studied a bit and got confused, can you please explain the delta x, which you said the data is spaced by.
Does it represent the time spacing at which the data was sampled?
As f(0), f(1), f(2) and f(3) are recorded at time x0, x1, x2, and x3. So delta x is x1-x0.

Thank you. Your video helped me a lot.

thank you very much I finally understood what's going on!

before delving into this video, viewer must have a complete and clear foundation from continuous signal processing and some sort of admath
