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
Signal frequency = 12 KHz
Carrier frequency = 2.51 Mz = 2510 KHz
`therefore` Upper side band frequency = 2510 +12 = 2522 KHz
Lower side band frequency = 2510 -12 = 2498 KHz
