Question:
In amplitude modulation,
In amplitude modulation,
Show Hint
In amplitude modulation, remember that only the amplitude of the carrier wave is modulated by the information signal.
Updated On: Jan 27, 2026
- both amplitude and frequency do not change according to information signal.
- amplitude remains constant but frequency changes according to information signal.
- both amplitude and frequency change according to information signal.
- amplitude of carrier wave changes according to information signal.
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding amplitude modulation.
In amplitude modulation (AM), the amplitude of the carrier wave varies according to the information signal, while the frequency remains constant.
Step 2: Conclusion.
Thus, the correct answer is (D) amplitude of carrier wave changes according to information signal.
