AM Advantage:AM is the simplest type of modulation. Hardware design of both transmitter and receiver is very simple and less cost effective.AM Disadvantage:AM is very susceptible to noise.Application:AM radio broad cast is an example

1.9

FM Advantage:Modulation and demodulation does not catch any channel noise.FM Disadvantage:Circuit needed for FM modulation and demodulation is bit complicated than AMApplication:FM radio broad cast is an example

1.10

PM Advantage:Modulation and demodulation does not catch any channel noise.PM Disadvantage:Circuit needed for PM modulation and demodulation is bit complicated than AM and FMApplication:Satellite communication.
