What is the main disadvantage of FM over AM?(a) high modulating power

1.	What is the main disadvantage of FM over AM?(a) high modulating power is needed(b) noise is very high for high frequencies(c) high output power is required(d) large bandwidth is requiredThis question was posed to me by my school principal while I was bunking the class.I need to ask this question from Demodulation of SSB with Large Carrier in section SSB Modulation of Analog Communications
Answer» The correct choice is (d) large bandwidth is required The best I can explain: The DISADVANTAGE of FM over AM is that in frequency modulation large bandwidth is required. While, in CASE of advantages, FM is less prone to noise interference and has lower power CONSUMPTION compared to AM.
