How many Fourier transforms are there?
There are four classes of Fourier transform, which are represented in the following table.
So far, we have concentrated on the discrete Fourier transform. * The class of the Fourier transform depends upon the nature of the function which is transformed.
What is the formula of Fourier transform?
Using the Fourier transform formula we have ^f(ω)=∫d−d1. e−iwxdx=[e−iωx−iω]d−d=−1iω(e−iωd−ei.
What is the full formula for the FFT?
V The Fast Fourier Transform
In the FFT formula, the DFT equation X(k) = ∑x(n)W_N^nk is decomposed into a number of short transforms and then recombined.
The basic FFT formulas are called radix-2 or radix-4 although other radix-r forms can be found for r = 2^k, r > 4.
The Fourier Transform is a mathematical technique that transforms a function of time, x(t), to a function of frequency, X(ω).
It is closely related to the Fourier Series.

Forward and Inverse Fourier Transform

F ( k ) = F x [ f ( x ) ] ( k ) = ∫ − ∞ ∞ f ( x ) e − 2 π i k x d x.
f ( x ) = F k − 1 [ F ( k ) ] ( x ) = ∫ − ∞ ∞ F ( k ) e 2 π i k x d k.
The symbols used to denote the forward and inverse Fourier transform are given as follows:
