1 Answer

Answer :

The process of converting digital signal to analog signal is called modulation and demodulation. Data communication is the combined result of both modulation and demodulation process. In order to facilitate communication, modulation of the transmitted signal and demodulation of the received signal are done by using modem at both the sender and the receiver.
