How to Do FFT in MATLAB

Learn how you can do Fast Fourier Transform (FFT) in MATLAB. It starts with generating a synthesized signal and then using the FFT function to convert the signal from the time domain to the frequency domain, finally showing how to determine the sinusoid components of the signal in the frequency domain. Zero-padding and windowing methods are also introduced for spectrum analysis when the signal duration does not contain an integer number of signal cycles.

The video for which I was looking for a long time. Thank you so much for this video and your easy to understand explanation.

[@SyedAbdulRahmanKashif]

Well explained basic concept of FFT. Thank you so much.

[@linamohammed6657]

Thanks a lot.. It's nice to find someone who explain things easily

[@med7756]

Best video ever thank you from my heart
helped alot
you're amazing
you're my everything

[@laurencamila9024]

this is too good. Thank you

Thank you so much, greetings from Bimac Research group - Universidad del Cauca, Colombia.

Great video, she has such a lovely voice.

Thanks for the video!! Can we go over maybe changing the fft to a one side fft?

When you decrease the duration from 2 to 0.64, I got an error for phase1: “Array indices must be positive integers or logical values”. With duration of 2 it was correct. There was also the error, when I added Zero-padding and windowing. When I change back to 2s, the error disappeared, but all phase-values are wrong.

Thanks

Thank you, well explained ! Could you make a video explaining the 2DFFT with image filtering?

The time "t" is missing in the equation at 0m49s in the video
