In an amplitude modulation with modulation index 0.5 the ratio of the carrier wave to that of side band in the modulated wave is

A

`4:1 `

B

`1:1`

C

`1:2 `

D

`2:1`

Text Solution

Verified by Experts

The correct Answer is:
A
Here, modulation index, `mu =0.5 `
Amplitude of the carrier wave `= A_C`
Amplitude of the side band `= mu A_c/2`
Their ratio `=2/mu =2/(0.5) =4/1`

Both amplitude modulation (AM) and frequency modulation (FM) are used for radio broadcasting. The amplitude of the high frequency carrier wave is varied or modulated in accordance with the variations in the amplitude of the audio signals that are to be transmitted, in te process of amplitude modulation in frequency modulation te amplitude of the carrier remains constant but its frequency is varied inn accordance withh the audio signal.
