Advantages of FM

1. The depth of modulation of the frequency modulated wave in FM is independent of amplitude,whereas in the AM it is independent on these parameters.
2. Because of the frequency allocation,there is less channel interference than in the AM.
3. In FM,the noise can be reduced by increasing the frequency deviation.In the AM,we do not have this one.
4. In FM,we can reduce the large noise by increasing the signal-to-noise ratio.
5. The transmitter in FM can operate at higher frequency such as VHF and UHF ranges so that,radius of reception is limited.
