What is frequency Fourier transform?

A Fourier transform (FT) is a mathematical transform that decomposes functions into frequency components, which are represented by the output of the transform as a function of frequency.

What is FFT in frequency domain?

The "Fast Fourier Transform" (FFT) is an important measurement method in the science of audio and acoustics measurement. It converts a signal into individual spectral components and thereby provides frequency information about the signal.

What are the two types of FFT?

These are called the radix-2 and mixed-radix cases, respectively (and other variants such as the split-radix FFT have their own names as well).

What is FFT formula?

The fast Fourier transform has become a major DSP tool since being popularized by Cooley and Tuckey in 1965. In the FFT formula, the DFT equation X(k) = ∑x(n)WNnk is decomposed into a number of short transforms and then recombined.
