A message signal of peak value 2 V is used to modulate a carrier wave of peak value 10 V . The modulation
index of the amplitude modulated wave is:
- A 0.2
- B 5
- C 0.66
- D 1.5
Answer & Solution
Correct Answer
(A) 0.2
Step-by-step Solution
Detailed explanation
\( \mu = \frac{A_m}{A_c} \) \( \mu = \frac{2\,V}{10\,V} \) \( \mu = 0.2 \)
