Re: Usage of Fourier transforms...

There are: Discrete Fourier Transform and Continuous Fourier Transform.
And there a lot of algorithms to calculate Fast Fourier Transform (the
Discrete Fourier Transform). I think it is what he would like to mean.

There are also the Fourier Series, but that is not a integral
transform.

Hi all, this topic is of electronics-communication interest. Here my
query is, what is the usage of Fourier transform ? Why it is so widely
used in image processing and communication equipments ? Please suggest.

A lot of different transforms share the generic name 'Fourier
Transform'. A common use is to separate the various components in some
signal for analysis and processing. That's a very broad statement, and
I suggest you look at some resources for yourself to understand what
use that can be.


huh? Theres only one fourier transform!
