Advantages and Disadvantages of FM over AM

The advantages and disadvantages of FM over AM are populated below:
Advantages:
>> The primary advantages of FM over AM is its immunity to noise
>> Noise is short-duration amplitude variations caused by lightning, motors, auto-ignitions, power transients and other sources
>> Another advantages of FM over AM is the capture effect that allows the strongest signal on frequency to dominate without interference from the other signal
>> FM has greater transmitter efficiency since Class C amplifier may be used
 
Disadvantages:
>> FM has wide bandwidth compared to AM
>> The spectrum space taken up byFM signal may be limited by carefully controlling the deviation ratio.
>>Circuits used in FM to produce and demodulate FM is more complex and expensive than AM circuits.
