A signal wave of frequency 12 kHz is modulated with a carrier wave of frequency 2-51 MHz. The upper and lower side band frequencies are respectively.

A

2512 kHz and 2508 kHz

B

2522 kHz and 2488 kHz

C

2502 kHz and 2498 kHz

D

2522 kHz and 2498 kHz

Text Solution

Verified by Experts

The correct Answer is:
D
Upper side band (USB) frequency `=f_(c)+f_(m)`
`=(2.51) MHz+(12) kHz =2522 kHz `
Lower side band (LSB) frequency`=f_(c)-f_(m)`
`=(2510-12)kHz=2498kHz `
