When the modulating signal controls the frequency of the carrier, we get______________?
Correct answer: C. Frequency modulation
- A. Phase modulation
- B. Amplitude modulation
- C. Frequency modulation
- D. May be any one of the above
Explanation
Frequency modulation occurs when the instantaneous frequency of the carrier varies according to the modulating signal. Amplitude modulation changes carrier amplitude, while phase modulation changes carrier phase.
