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

A

2005 kHz, 2000 kHz and 1995 kHz

B

2000 kHz and 1995 kHz

C

2 MHz only

D

2005 kHz and 1995 kHz

Text Solution

Verified by Experts

The correct Answer is:
A
Amplitude modulated wave consists of three frequencies are `omega_c + omega_m , omega, omega_c - omega_m`
i.e. 2005 KHz, 2000 KHz, 1995 KHZ
