Question

Draw backs of Amplitude modulation :

• A. During transmission extra noise creeps in.
• B. Most of the transmitting power is wasted, as it does not contain useful information.
• C. The reception is not clear in the case of weak signals due to noise
• D. The reciever set is complex

Answer 1

Answer: (A), (B), (C)

The correct options are
A During transmission extra noise creeps in.
B Most of the transmitting power is wasted, as it does not contain useful information.
C The reception is not clear in the case of weak signals due to noise

In amplitude modulation the receiver set is not at all complex rather it is pretty easy to make. But it is prone to addition of noise which makes signals difficult to understand. More power is required to change the amplitude of the carrier wave. Since the noise creeps in, the weaker signals are not clear.
