The modulation index of an FM signal is ...

The modulation index of an FM signal is 1.5. The modulating frequency is 5 KHz. What is the maximum frequency deviation ?

A

A. 5 KHz

B

B. 6 KHz

C

C. 7.5 KHz

D

D. 9 KHz

Text Solution

Verified by Experts

The correct Answer is:
C
Modulation index `(m or mu) = (delta_"max")/(f_m)`
`therefore delta_"max"=muxxf_m=1.5xx5xx10^3=7.5xx10^3`=7.5 KHz
