which sort of communication is better for distant commn? AM or FM? why..

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.
