Advantages and disadvantages of FM and AM modulation

Advantage of AM

1- Corverage area of AM Reciever is wider than FM because atmospheric propagation
2- AM is long distance propagation because λ
3- AM Circuit is cheapter and non complex than FM.
4- AM have bandwidth limited and FM unlimited
Disadvantage of AM

1- The only one way to withance to noise happen is increasing power transmite
2- Signal of AM is not stronger than FM when it propagate to obstacle. (Urband)
3- Only one sideband of AM transmites Information Signal, So it loss power on other sideband and Carrier.
4- Noise mixes AM Signal in amplitude when it propagates in free space that it make difficulty to recover Original Signal at reciever.
