If in an amplitude modulated wave, the maximum amplitude is 14 V and the modulation index is 0.4, then the amplitude of the carrier wave is
- A 4 V
- B 8 V
- C 12 V
- D 10 V
Answer & Solution
Correct Answer
(D) 10 V
Step-by-step Solution
Detailed explanation
\(A_{max} = A_c (1 + \mu)\) \(14 = A_c (1 + 0.4)\) \(A_c = \frac{14}{1.4}\) \(A_c = 10\) V
