The modulation frequency of an AM radio ...

The modulation frequency of an AM radio station is 250 kHz, which is 10% of the carrier wave. If another AM station approaches you for license what broadcast frequency will you allot ?

A

2000kHz

B

2900kHz

C

2750kHz

D

2250kHz

Text Solution

Verified by Experts

The correct Answer is:
A
Range = 2250 kHz to 2750 kHz
`2500pm250`
For 2900 kHz range is which falls in the given range
Falls in given range
2250 kHz & 2750 kHz also fall within the given range
Only 2000 kHz is permissible as range for it is 1750 kHz – 2250 kHz
