Hi all, I am having trouble with computing the Fourier Transform of a shifted AND scaled Heaviside function. Basically I can get: FourierTransform[HeavisidePi[(x + a)], x, \[Xi]] = (E^(-I a \[Xi]) Sinc[\[Xi]/2])/Sqrt[2 \[Pi]] or FourierTransform[HeavisidePi[(x/b)], x, \[Xi]] = (Abs[b] Sinc[(b \[Xi])/2])/Sqrt[2 \[Pi]] but when I combine [(x + a)/ b] i get nothing! Any clue?? Thank you!
