Repeat Prob. 1.2-4 using

(a) a = 1/3 and b = 1/2

(b) a = 1/3 and b = −1/2

(c) a = −1/3 and b = 1/2

(d) a = −1/3 and b = −1/2

Prob. 1.2-4

Using x(at + b) shown in Fig. P1.2-4, sketch the original signal x(t) if

(a) a = 2 and b = 1

(b) a = 2 and b = −1

(c) a = −2 and b = 1

(d) a = −2 and b = −1
