WebComparing equation (6) with the Fourier Series given in equation (1), it is clear that this is a form of the Fourier Series with non-integer frequency components. Currently, the most common and e cient method of numerically calculating the DFT is by using a class of al-gorithms called \Fast Fourier Transforms" (FFTs). The WebThe Fourier transform of a function of x gives a function of k, where k is the wavenumber. The Fourier transform of a function of t gives a function of ω where ω is the angular frequency: f˜(ω)= 1 2π Z −∞ ∞ dtf(t)e−iωt (11) 3 Example As an example, let us compute the Fourier transform of the position of an underdamped oscil-lator:
