Answer 2

Answer:

Advantages

-Amplitude Modulation is easier to implement.

-Demodulation can be done using few components and a circuit.

Disadvantages

-When it comes to power usage it is not efficient.

-It requires a very high bandwidth that is equivalent to that of the highest audio frequency.
