In an amplitude modulation with modulation index 0.5, the ratio of the amplitude of the carrier wave to that of the side band in the modulated wave is
- 4 : 1
- 1 : 4
- 1 : 2
- 2 : 1
Solution
Modulation index, $\mu=0.5=\frac{1}{2}$
$\frac{A_{S B}}{A_C}=\frac{\mu}{2}=\frac{1}{4}$
or $\frac{A_C}{A_{S B}}=\frac{4}{1} \text { or } 4: 1$
