Disadvantages of FM over AM

Disadvantages of FM over AM are

Options:

prone to selective fading
capture effect
poorer signal to noise ratio at high audio frequencies
all of the above

Correct Answer: all of the above

Explanation:

FM systems have a much wider bandwidth than AM systems and therefore more prone to selective fading. FM receiver has a tendency to capture one transmitting station only called capture effect. FM transmitter and receiver require booster circuits as they have poorer signal to noise ratio at high audio frequencies.
