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
The formula for modulating index is given by
`m_(f)=(delta)/(v_(m))= ("Frequency variation")/("Modulating frequency") =(10xx10^(3))/(2xx10^(3))=5`
