Fast Fourier transform

[RITESH KAKKAR]

Hello,
The FFT separates the different frequency carring in signal of information.
But i dont understand how we make/build procedure of these instruments is FFT work in Digital processor or can be build by analog circuit also?

Hi,

again: all the information is available in the internet. Many times. With algorithms, code, descriptions... I assume even videos.

google "FFT butterfly" or "FFT algorithm".

Read them. Then... if you encounter SPECIFIC questions...you are welcome to ask them here.

***
FFT as analog: I don´t think so.
There are optical (F)FT systems.

Analog DCT

Although this is DCT, it can be applied to DFT.

IEEE papers are not free to download.. that is why it is not opening... unless you do some other stuff.

 

[RITESH KAKKAR]

ok, why it is not free sir.
and what makes IEEE special?

 

[CataM]

What is IEEE?

 

[RITESH KAKKAR]

please tell more about FFT how it separate frequency?
and how digital modulator work does digital also have several frequency?
