The signals in Figure are zero except as shown.

(a) For the signal x(t) of Figure (a), plot

(i) 4x(t) – 2

---

(ii) 2x(t) + 2

---

(iii) 2x(2t) + 2

---

(iv) –4x(t) + 2

Verify your results by checking at least two points.

---

(b) Repeat Part (a) for the signal x(t) of Figure (b).

---

(c) Repeat Part (a) for the signal x(t) of Figure (c).
