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 modulation is given by `m_f=("Frequency variation " (delta v))/("Modulating frequency "(v_m))=(10xx10^3)/(2xx10^3)=5`
