1. Why is it desirable to have the modulation index of an AM signal as large as possible without overmodulating?
2. Describe what happens when a typical AM modulator is overmodulated, and explain why overmodulation is undesirable.
3. Describe three different ways in which the modulation index of an AM signal can be measured.
4. WHY and by HOW MUCH does suppressing the carrier improve the efficiency of an AM signal?
5. WHY and by HOW MUCH does eliminating one sideband improve the efficiency of an AM signal?
