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

`10%`

B

`20%`

C

`25%`

D

`50%`

Text Solution

Verified by Experts

The correct Answer is:
D
Here, `V_(max)+(24)/(2)=12mV` and `V_(min)=(8)/(2)=4mV`
Now, `m=(V_(max)-V_(min))/(V_(max)+V_(min))=(12-4)/(12+4)=(8)/(16)=(1)/(2)=0.5=50%`
