In case of FM,we have to vary the frequency according to
the modulating frequency and amplitude remains costant
thats why to eliminate the losses due to the amplitude is
very small that is required for clear sound.
In second case the amplitude of the incoming signal varies
and the frequency remains constant that is required for
sharp and clear picture.
