(a) Consider the two-LTI system cascaded in Figure. The impulse responses of the two systems are identical, with h1(t) = h2(t)= e–t u(t). Find the impulse response of the total system.

---

(b) Repeat Part (a) for the case that h1(t) = h2(t) = δ(t).

---

(c) Repeat Part (a) for the case that h1(t) = h2(t) = δ(t – 1).

---

(d) Repeat Part (a) for the case that h1(t) = h2(t) = u(t – 2)– u(t – 4).
