Question 11: Let x(t) = u(t-2)-u(t-4) +5(1-6) and h(t)= eu(t). Compute y(t)= x(t) *h(t).

Sketch Y(t) = u(t) 3(t-2) + 5u(t-4) -

a) For the system x (t) hG) find y (t) forn x(t) = etu(-t) and h() =Qu(t) -u(t-1) -u(t~2) G) x (+) = euc-t) and ht) = 2u (1-t)

Let x(t) = u(t) - u(t-1) and y(t) = u(t) + u(t-1)-2u(t-2) (a) plot x(t) and y(t) (b) evaluate graphically and plot z(t) x(t) * y(t)
