Answer Posted / shweta
modulation is needed to transfer the signal from
transmitter to reciever. As the signal passes from
transmmiter to reciever there are many external effects
such as noise and other factors which can degrade the
signal so there is a need of modulation so that the signal
cant become so much week that it cant reach the reciever.
If the signal is sent without modulating then it will get
degraded due to external effects.
