Question

what is amplitude modulation? discuss its advantages and disadvantages​

Answer 1

$\huge\underbrace\purple{Answer}$

An amplitude modulation signal is not efficient in terms of its power usage. Power wastage takes place in DSB-FC (Double Side Band – Full Carrier ) transmission. It is not efficient in terms of its use of bandwidth. It requires a bandwidth equal to twice that of the highest audio frequency.

An amplitude modulation signal is not efficient in terms of its power usage. Power wastage takes place in DSB-FC (Double Side Band – Full Carrier ) transmission. It is not efficient in terms of its use of bandwidth. It requires a bandwidth equal to twice that of the highest audio frequency.

The advantages of amplitude modulation include the following.

• Amplitude modulation is economical as well as easily obtainable
• It is so simple to implement, and by using a circuit with fewer components it can be demodulated.
• The receivers of AM are inexpensive because it doesn’t require any specialized components.

The disadvantages of amplitude modulation include the following.

• The efficiency of this modulation is very low because it uses a lot of power
• This modulation uses amplitude frequency several times to modulate the signal by a carrier signal.
• This declines the original signal quality on the receiving end & causes troubles in the signal quality.
• AM systems are susceptible toward the generation of noise generation.
• The applications of amplitude modulation limits to VHF, radios, & applicable one to one communication only
