Answer Posted / radhar
for example if a person is sitting at the bus to go to hyd.
there is a bus which will go to the hyd. it is not the
matter that if the bus goes to the hyd he will also go.
he will also go to the hyd only when he sit in the bus.
here the bus is the carrier & the man is the information.
from this it is clear that modulation is why because the
information which is having less power can't travel large
distances that will put on the carrier which is having
large power that it can travel large distances.
