Summary

Fourier transform of the rect function and sinc functions. The continuous Fourier transform takes an input function f(x) in the time domain and turns it into a new function, Æ’Ì‚(x) in the frequency domain. In the first part of the animation, the Fourier transform (as usually defined in signal process
