FM is advantageous over AM as*2 pointsThe amplitude of FM is constant. So transmitter power remains unchanged in FM but it changes in AMThe depth of modulation in FM can be changed to any value by changing the frequency deviation. So the signal is not distortedThere is less possibility of adjacent channel interference due to presence of guard bandsAll of the above

Solution

The correct answer is "All of the above".

  1. The amplitude of FM is constant. This means that the transmitter power remains unchanged in FM, but it changes in AM. This is advantageous because it allows for a more consistent signal strength.

  2. The depth of modulation in FM can be changed to any value by changing the frequency deviation. This means that the signal is not distorted, which can improve the quality of the transmission.

  3. There is less possibility of adjacent channel interference due to the presence of guard bands in FM. This can prevent interference from other channels, which can improve the clarity of the transmission.

So, all of these factors make FM advantageous over AM.
