The Fourier transforms utility lies in its ability to analyze a signal in the time domain for its frequency content. ... The signal can then be analyzed for its frequency content because the Fourier coefficients of the transformed function represent the contribution of each sine and cosine function at each frequency. An inverse Fourier transform does just what youd expect, transform data from the frequency domain into the time domain.
Discrete Fourier Transforms
The discrete Fourier transform (DFT) estimates the Fourier transform of a function from a finite number of its sampled points.
