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

Options

A. A)`4:1`
B. `B)1:1`
C. `B)1:2`
D. `D)2:1`

Answer

A

Explanation

Modulation index `=0.5=(1)/(2)`
`A_("side band")=(muA_(c))/(2)`
`(A_("side band"))/(A_(c))=(mu)/(2)=(1)/(4)`
or `(A_(c))/(A_("side band"))=(4)/(1)`
