Answer Posted / girija shankar
BASIC NEED FOR MODULATION IS:
1.TO REDUCE ANTENNA HEIGHT
2.TRANSMIT THE INFORMATION TO MORE DISTANCE WITH OUT
INTERFERENCE
3.TO REDUCE BAND WIDTH
EX:SUPPOSE IF U WANT THROUGH A PAPER HAVING INFORMATION TO
YOUR OPP APPARTMENT FROM YOUR APPARTMENT(EX:D=500cm)IF U
SIMPLY THROUGH A PAPER IT WILL NEVER REACH TO THE OPP
APPARTMENT BUT IF YOU USE A STONE.i.e COMBINELY WE CAN
THROUGH BECAUSE STONE HAVE WEIGHT LIKE WISE CARRIER HAVE
MORE POWER THAN BASE SIGNAL THAN WE CAN TRANSMITE THE
SIGNAL.
