The Fourier transform is a generalization of the complex Fourier series in the limit as Replace the The Fourier transform of a derivative of a function f(x) is

(7) so that the Fourier and inverse Fourier transforms differ only by a sign Differentials: The Fourier transform of the derivative of a functions is given by F { df(x)

by functions like c(x) is easy] and Fourier domain [where operations like derivatives are easy] Almost invariably, FFT implementations compute DFTs and IDFTs

The reader will note a kind of reciprocity between this result and the previous one 4 Fourier transform of an nth derivative: F(f(n)(t)) = (iω)nF(ω)

The derivative property of Fourier transforms is especially appealing, since it turns a differential operator into a multiplication operator In many cases this allows us to eliminate the derivatives of one of the independent variables

below, we obtain integrable functions with an integrable derivative whose Fourier transforms decay slower than ξ−(1+ϵ), for any fixed positive ϵ > 0
