An FM signal has a resting frequency of ...

An FM signal has a resting frequency of 105MHz and highest frequency of 105.03MHz when modulated by a signal of frequency 5kHz. The carrier swing is

A

25 kHz

B

54 kHz

C

60 kHz

D

75 kHz

Text Solution

Verified by Experts

The correct Answer is:
C
Carrying Swing = `2 xx Deltaf `
`=2 xx 105 . 03 - 105 = 2 xx 0.03 MHz`
`=0.06 MHz = 60 kHz `
