Laplace transform of piecewise function

1 Answer. The function in questions is 1 on [ − a, a] and 0 elsewhere. So the Fourier transform of this function is. 1 2 π ∫ − a a e − i s x d x = 1 2 π e − i s x − i s | x = − a x = a = e i s a − e − i s a 2 π i s = 2 π sin ( s a) s. This is the "sinc" function, and you'll want to become familiar with this functon.
