Question:
In AM_______.
In AM_______.
Show Hint
In AM, remember: only the carrier's amplitude changes, not frequency or phase.
Updated On: Jun 23, 2025
- Carrier amplitude is varied
- Carrier frequency is varied
- One side band is produced
- Noiseless and high-fidelity reception is obtained
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
In Amplitude Modulation (AM), the amplitude of the carrier wave is varied in proportion to the instantaneous amplitude of the message signal, while frequency and phase remain constant.
Options 2–4 describe other forms of modulation (like FM or SSB) or outcomes not specific to AM.
