Question { 17657 }

what is the need for modulation?

Answer

for security purpose, to protect from noise,distortions
etc., modulation is used
so in order to transmit a signal ,modulation is done by
superimposing carrier signal on to the message signal
so when it is transmitted over the channel ,modulation
serves as a protective covering for the message signal.so at
the receiver side it is then demodulated to get the original
signal

Question { Ericsson, 11030 }

what is the features of GSM Technology and CDMA technology

particular no ,a code will be there this travels faster than
the information and checks the receiver which matches with
the code that was send from the transmitter if it matches
the information gets received,thus its more secure.
