The modulation index of an `FM` carrier having a carrier swing of `300kHz` and a modulating signal `10kHz` is

A

`15`

B

`10`

C

`20`

D

`25`

Text Solution

Verified by Experts

The correct Answer is:
A
`CS=2Deltaf`
`Deltaf=(CS)/(2)=(300KHz)/(2)=150 KHz`
`m_(f)=(Deltaf)/(f_(m))=(150KHz)/(10KHz)=15`
