A single of 5 kHz frequency is amplitude modulated on a carrier wave of frequency 2 MHz. The frequencies of the resultant signal is/are :-

A

2 MHz only

B

2005 kHz and 1995 kHz

C

2005 kHz, 2000 kHz and 1995 kHz

D

2000 kHz and 1995 kHz

Text Solution

Verified by Experts

The correct Answer is:
C
`f_m= 5 KHz`
`f_c = 2MH_z = 2000 KHz`
LSB `= f_c - f_m = 1995` KHz
USB = `f_c + f_m = 2005` KHz.
