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 2508KHz

B

2522KHz and 2488KHz

C

2502KHz and 2498KHz

D

2522KHz and 2498KHz

Text Solution

Verified by Experts

The correct Answer is:
D
Here,v,=1 2KHz,`v_(c)=2.51MHz=2510KHz`
The upper side band frequency =2510+12=2522 KHz
The lower side band frequency `=2510-12=2498KHz`.
