s²+1
(a) What is the Fourier transform X₁ (w) of the signal?
(b) Using the Laplace transform properties, find the Laplace transform of the following signal
x2(t).
x2(t) = e³ x₁(t−1)-4x₁(4)
Note, you do not need to simplify the expression of X2(s). However, state whether it is
possible to write X2(s) as a rational fraction (i.e. ratio of polynomials) in s.
