Answer / jatinderpal singh
need of modulation....
1.sme time signal is too small due to reseiver nt get that
signal...
so by the process of modulation we uses carrier waves
which modulate the signal so that it will not effected by
environment condition,,,it reduces
1,cost of antenna ,,instead of using large anteena we can
use here small anteenas

Answer / nithya
if v transmit t signals over large distances,it leads
to "interference".(i.e) the signals get interfer wit other
signals.

Answer / n.shalini
actually modulation is nothing but changing something.
so in communication why we using this modulation is that
to carryng one signal on another.
so without modulation we come across certain dificulties
such as practicability of antenna size, various noises,
interferences and all. so in the field of communication
without modulation we certainly having one signal which is
nothing but the information signal right.hence this simple
information signal usually possess low frequency(low
strength) cant be transmitted over our desired
destination.so in order to transmit this low strength
signals we require some boosting ie we require additional
frequency to transmit our signals right.this can be
accomplished by using high frequency carrier signals.so the
carrier signals carry the information signals over long
distances as our requirements without loss of any information.
