Question:
Over modulation occurs when modulation index 'm' is:
Over modulation occurs when modulation index 'm' is:
Show Hint
$m=1$ is 100 % modulation; $m>1$ is over-modulation (distortion).
Updated On: Jun 10, 2026
- $m > 1$
- $m < 1$
- $m = 1$
- $m = 0$
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept
Modulation index ($m$) defines the extent of modulation in AM signals.
Step 2: Analysis
If $m > 1$, the carrier wave is over-modulated, leading to distortion in the signal.
Step 3: Conclusion
Over-modulation occurs when $m > 1$.
Final Answer: (A)
