NettetIt is easy to calculate the Fourier transform Taking the inverse Fourier transform, we get ∫∞ − ∞(sin(ξ / 2) ξ / 2)2eixξdξ = 2πf(x), and the result follows. The second integral can be computed in a similar way. Just take f(x) = χ [ − 1, 1] (x) (the indicator function of the interval [ − 1, 1] ). Edit.
