High-level modulation is used:
A) in high-power applications such as standard radio broadcasting.
B) when the intelligence signal is added to the carrier at the last possible point before the transmitting antenna.
C) when the transmitter must be made as power efficient as possible.
D) all of the above.

Question

Quizplus · Accepted Answer

High-level modulation is used in scenarios described by all the given options: it is typical in high-power applications like standard radio broadcasting, involves adding the intelligence signal to the carrier just before the transmitting antenna to ensure efficient use of the transmitter's power, and is chosen to maximize the power efficiency of the transmitter.
