In this problem we examine the efficiency of AM for the case in which the message signal does not have symmetrical maximum and minimum values. Two message signals are shown in Figure 3.34. Each is periodic with period T, and τ is chosen such that the DC value of m(t) is zero. Calculate the efficiency for each m(t) for α = 0.7 and α = 1.
