Why Do We Use The Fourier Transform

Why Do We Use Fourier Transform First and foremost, a fourier transform of a signal tells you what frequencies are present in your signal and in what proportions. example: have you ever noticed that each of your phone's number buttons sounds different when you press during a call and that it sounds the same for every phone model?. In particular, the scaling property of the fourier transform may be seen as saying: if we squeeze a function in x, its fourier transform stretches out in ξ. it is not possible to arbitrarily concentrate both a function and its fourier transform.

Fourier Transform Betterexplained This fact is the central philosophy behind fourier transforms (fourier was very french, so his name is pronounced a little wonky: “4 e yay”). a complicated signal can be broken down into simple waves. this break down, and how much of each wave is needed, is the fourier transform.
