Application +4 | -1

A message signal of frequency

10 \mathrm{~kHz}

and peak voltage of 10 volts is used to modulate a carrier of frequency

1 \mathrm{~MHz}

and peak voltage of 20 volts. The side bands are

1010 \mathrm{~kHz}

and _____

\mathrm{kHz}

.

View answer and explanation

Correct option: A

990

Option A (990) is correct because the sidebands in amplitude modulation are the carrier frequency plus and minus the message signal frequency.
