TI Precision Labs - ADCs: Fast Fourier Transforms (FFTs) and Windowing

This video introduces the Fast Fourier Transform (FFT) as well as the concept of windowing to minimize error sources during ADC characterization.

Thank you Lord Jesus, for this video. I've been searching the internet for hours to understand why my FFT outputs were seemingly wrong.

[@markuscwatson]

I love TI! Thanks for this!

[@charlesgeorge85]

This is one of the best tutorial, Thanks for the effort..

[@BrannFangs]

Excellent video, thanks!

How do you ensure the end of the record falls within the right part of the window? Or what is to keep the end of record from falling in the middle of the window?

Brief and clear

This is gold. Thanks!

great video, thanks!

What changes to occur when we use 2 and after that we use 3, what effect does it have on results???
This is a very nice video..!!!!!!!!!!

[@mayurwagh8361]

superb explanation

[@binli307]

thank you!!!

It is worth noting that the alias region is conjugate symmetric about Fs/2.

[@Gaygurke]

for real signals -> in use with adc yes

[@bassome3000ify]

Does TI offer a chip that can convert analog signals to FFT values? I.e. analog input, serial digital output

[@jsogman]

Hello, did you ever find something like this?

[@PalgunaGopireddy]

Much elaborated vid

Thanks!

Hello everyone! This Fast Fourier Transfirm system in the inverting version can perfectly supervise the current generation of two sine functions offset by an angle of 90 degrees to each other. They would power the next generation Brushless Hybrid Fast - Rotation Motor (BLHF-RM). I have already described this issue in numerous publications.
Greetings to fans of synchronous motors 😀.

0:39 that is DFT equation not FFT, please don't mix that; FFT is a solution to DFT which is a lot faster than other methods available.

[@jazzjohn2]

The FFT is an optimised method to compute the DFT. The result is the same, so she wasn't far off referring to the DFT equation as an FFT.

@@jazzjohn2 ну так люди приходят сюда посмотреть как из ДПФ получается БПФ. если бы я хотел посмотреть про ДПФ, я и искал бы видос про ДПФ, а не про БПФ

The 973.5 kHz on the graph should be 937.5 kHz
