The maximum peak ro peak voltage of an AM wire is `24 mV` and the minimum peak to peak voltage is `8mV`. The modulation factor is

A

0.1

B

0.2

C

0.25

D

0.5

Text Solution

Verified by Experts

The correct Answer is:
D
Peak to peak voltage = 24 mV
`therefore V_"max"=24/2` = 12 mV and `V_"min"=8/2` = 4 mV
`therefore` Modulation index or factor , `m=(V_"max" - V_"min")/(V_"max"+ V_"min")=(12-4)/(12+4)=1/2`=50%
