A carrier frequency of 1 MHz and peak value of 10 V is amplitude modulated with a signal frequency of 10 KHz with peak value of 0.5 V. What are the values of the modulation index and the side band frequencies ?

A

0.05 and 1 `pm` 0.010 MHz

B

0.5 and 1 `pm` 0.010 MHz

C

0.05 and 1 `pm` 0.05 MHz

D

0.5 and 1 `pm` 0.005 MHz

Text Solution

Verified by Experts

The correct Answer is:
A
Modulation index,
`m=A_m/A_c`
`m=(0.5V)/(10V)=0.05`
The side bands frequencies are `v_(SB)=v_c pm v_m=1 pm 0.010`MHz.
