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
`f_c = 2.51 MHz = 2510 KHz `
`f_m =` 12 KHz
LSB `= f_c-f_m ` = 2498 KHz
USB = `f_c+f_m = 2522` KHz.
