For an amplitude modulated wave, the modulation index is found to be 0.5. If the maximum amplitude is found to be 10.0 V, then the minimum amplitude is
- A 5.0 V
- B 3.33 V
- C 2.5 V
- D 6.66 V
Answer & Solution
Correct Answer
(B) 3.33 V
Step-by-step Solution
Detailed explanation
As \(\mathrm{m}=\frac{\mathrm{A}_{\max }-\mathrm{A}_{\min }}{\mathrm{A}_{\max }+\mathrm{A}_{\min }}\) \(\Rightarrow \quad 0.5=\frac{10-\mathrm{A}_{\min }}{10+\mathrm{A}_{\min }} \Rightarrow \mathrm{A}_{\min }=3.33 \mathrm{~V}\)
