The intuition is that Fourier transforms can be viewed as a limit of Fourier series as the period grows to in nity, and the sum becomes an integral. R 1 1 X(f)ej2ˇft df is called the inverse Fourier transform of X(f). Notice that it is identical to the Fourier transform except for . Fourier transforms are a tool used in a whole bunch of different things. This is an explanation of what a Fourier transform does, and some different ways it can be useful. And how you can make pretty things with it, like this thing. Fourier Transform Since this object can be made up of 3 fundamental frequencies an ideal Fourier Transform would look something like this: A Fourier Transform is an integral transform that re-expresses a function in terms of different sine waves of varying amplitudes, wavelengths, and phases.
