Which of the following is NOT the advantage of amplitude modulation? Correct Answer It is efficient in terms of its power usage

Advantages OF AM:

• It is simple to implement.
• It can be demodulated using a circuit consisting of very few components.
• AM receivers are very cheap as no specialized components are needed.

Disadvantages of AM:

• It is not efficient in terms of its power usage.
• It is not efficient in terms of its use of bandwidth, requiring a bandwidth equal to twice that of the highest audio frequency.
• It is prone to high levels of noise because most noise is amplitude-based and AM detectors are sensitive to it.
