An oscillator is producing FM waves of requency `2kHz` with a variation of `10kHz`. What is modulating index?

A

`0.20`

B

`5.0`

C

`0.67`

D

`1.5 `

Text Solution

Verified by Experts

The correct Answer is:
B
Modulating index in frequency modution is given by
`mg=("Frequency variation"(delta_(y)))/("Modulating frequency")`
`=(10 xx 10^3)/( 2 xx 10^(3))`=5
