Significance of modulation in communication.
written 5.5 years ago by | modified 2.6 years ago by |
Modulation is the process in which amplitude frequency phase of carrier signal is varied with respect to instantaneous amplitude of the modulating signal.
Need of modulation:
1] Reduction in the height of antenna.
2] Avid mixing of signals.
3] Increases the range of communication.
4] Allows multiplexing of the signals.
5] Improves quality of reception.
