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

The correct option is B 2005 kHz, 2000 kHz and 1995 kHzfc=2MHz=2000KHzfm=5KHzThe resultant frequencies are: fc−fm, fc, fc+fmThus, the frequencies are 1995, 2000 and 2005 KHz.

A signal of $5 k H z$ frequency is amplitude modulated on a carrier wave of frequency $2 M H z$ . Frequencies of the resultant signal is/are

The correct option is B $2005 k H z$ , $2000 k H z$ and $1995 k H z$
$f_{c} = 2 M H z = 2000 K H z$
$f_{m} = 5 K H z$
The resultant frequencies are: $f_{c} - f_{m}$ , $f_{c}$ , $f_{c} + f_{m}$

Thus, the frequencies are $1995$ , $2000$ and $2005 K H z$ .
