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: WebAnalysis of Fourier series becomes important because this method is used to represent the response of a system to a periodic input and the response depends on the frequency content of the input. Dirichlet Conditions: The conditions that a function f x may be expressed as Fourier series are known as the Dirichlet conditions.
