The modulation index of an `FM` carrier having a carrier swing of `200kHz` and a modulating signal `10kHz` is

A

`5`

B

`10`

C

`20`

D

`25`

Text Solution

Verified by Experts

The correct Answer is:
B
`CS=2`' `Deltaf` or `Deltaf=CS//2`
`Deltaf=(200)/(2)=100kHz`, Now `m_(f)=(Deltaf)/(f_(m))=(100)/(10)=10`
