Which type of analog modulation changes the number of waves representing one cycle?
A) amplitude modulation
B) frequency modulation
C) phase modulation
D) relative modulation

Question

Quizplus · Accepted Answer

Frequency modulation changes the frequency of the carrier wave to represent the modulating signal. It does not change the amplitude or the phase of the carrier wave. Amplitude modulation changes the amplitude of the carrier wave, phase modulation changes the phase of the carrier wave, and relative modulation is not a recognized form of analog modulation.
