Answer / raj
AM is better for distant communication.FM is used only for
small geografical areas.line of sight propagation is used
in fm.in AM we can transmitsignals to long distances.

Answer / jagdish hatwar
AM Broadcast is more usefull FOR LONG DISTANCE
COMMUNICATION than FM as it is more freq. range than FM.
| Is This Answer Correct ? | 4 Yes | 1 No |
Answer / charanya ganesh
fm communication system is preferred than AM comm. sys.
since amplitude of signal sensitive to noise in the
atmosphere than frequency.. hence fm is preferred

Answer / ramesh maharjan
Electromagnetic waves amplitude fades as distance increases and in AM amplitude is key parameter to regenerate the signal, so for distant communication AM is not suitable.
Where as in FM amplitude is not a major parameter for signal regeneration, so it is suitable to use FM considering quality and interference factor.

Answer / manish godwany
FOR DISTANCE COMMUNICATION FM SYSTEM IS BETTER BECAUSE
FREQUENCY IS THE MAIN PARAMETER OF REGENERATION WHICH IS
LESS EFFECTED WITH DISTANCE WHEREAS IN CASE OF AM
AMPLITUDE IS THE PARAMETER OF REGENERATION WHICH IS MORE
EFFECTED WITH DISTANCE.

Answer / aseef
FM COMMUNICATION IS BETTER FOR THE DISTANCE COMMUNICATION
BECAUSE IN AM THERE IS MORE CHANCESS OF INTEREFERENCE AND
IT CANT TRAVEL MORE DISTENCE WHEREAS IN FM THE INFORMATION
IS SEND IN THE FORM OF FREQUENCY WHICH CAN TRAVELLES LONG
DISTANCE WITHAOUT INTEREFERENCE.
