Disadvantages of FM over AM
Q. Disadvantages of FM over AM are- Published on 14 Oct 15a. Prone to selective fading
b. Capture effect
c. Poorer signal to noise ratio at high audio frequencies
d. All of the above
ANSWER: All of the above
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.
