Obtain B90 for the following signals if it is defined. If it is not defined for a particular signal, state why it is not.
(a) x1 (t) = e-at u(t), where α is a positive constant
(b) x2 (t) = 2W sinc (2W t) where W is a positive constant
(c) x3 (t) = II (t/Ï) (requires numerical integration)
(d) x4 (t) = Î (t/Ï) (requires numerical integration)
(e) x5 (t) = e-a|t|
