1. Discuss what will happen to the modulation process of an amplitude modulation (AM) signal if the carrier signal level remains constant and the sideband signal level increases and justify your answer 2. A normal modulation usually has a modulation index ranges from 0 to 1 but in some rare cases, the modulation index can be greater than 1. Discuss what will happen to the output of the receiver if this situation happens.
