Where is Frequency in the output of the FFT?

I am Christian and I bless you Mark. Be Strong !!! about the current juncture in Israel.

Thank you for the recording! I am fighting to understand FFT and your video is awesome!

👍👍👍👍👍👍👍👍

您好，非常感谢您的辛苦付出，请问你的书籍有中文版吗？

Thanx! 😊

What a charming video! I'm struggling to understand how the DFT is useful for studying the frequencies of a signal, and this video helped me a lot!

Mazel tov! Your videos are amazingly helpful! 😃💯💥👍🥳

Why we ignore the complex numbers during the calculation frequency ? we integrated the index number of complex numbers but I didn't understand clearly that ignoring the complex numbers value ? I will be glad if someone reply this question. Apart from this question, illustrations perfect for understand. Thank you for your great effort.

You are very professional. Thank you very much 🥰 for your great video. Much of efforts done within just 7 minutes.

Thank you very much Mark

Great video thanks.

One book sold :)

This video deserves many more views. Thank you so much for all the work you put in!! The production value is super high.

Mark you are an absolute blessing especially for all those interested in this field . Your teaching style is superb. Just wanted to say thank you and please continue with these amazing video lessons

Thank you.
Can you explain how Matlab choose R?
When I apply fft(data) I don't tell matlab what is my sampling rate

Please explain about fractional Fourier transform(FRFT), since the first notion that initiate the birth of the concept of the FRFT itself, about the time-frequency plane rotation which is one of the most complicated stuff to understand, also the applications and how far FRFT can be applicable as we can reach

Sir when will your book on Fourier series available on Amazon in India

I've learned the fourier transform years ago but I love these videos because they help the concepts really sink in. If you ever covered how to interpret the results of the fourier transform in two dimensions I would be grateful because I haven't found any videos that explain it very well.

This knowledge is not necessary for the work I do, but I love learning how such analysis is done! Excellent presentation and instruction, sir!

You are an international treasure. Keep up the amazing work!

I can answer you question: how to calculate the phase?

because each the value is a complex number, which is a vector, the angle of x-axis is the phase.

Thank you very very much!
I learned Fourier Transfrom Now!

Wish you will make more better videos:-)
