Question: Three message signals are periodic with period T, as shown in Figure 3.32. Each of the three message signals is applied to an AM modulator.

Three message signals are periodic with period T, as shown in Figure 3.32. Each of the three message signals is applied to an AM modulator. For each message signal, determine the modulation efficiency for Î± = 0.2, Î± = 0.3, Î± = 0.4, Î± = 0.7, and Î± = 1.
