Question

Give the advantages of a digital communication system.

Answer 1

Hint:Recall the basics of the digital communication system. Recall the different advantages of the digital communication system depending on the process of information transfer, effect of external elements on the input and output signals, quality of the output signal, range of communication, cost, etc.

Complete step by step answer:
Digital communication is the type of communication in which digitally encoded information is transferred by the electronic transmission process.
 The advantages of the digital communication system are as follows:
1. The quality of the transmitted signal is high.
2. The digital communication can occur for any distance between the two terminals of the communication system.
3. The input signal used in the digital communication system is provided with an added security.
4. The digital communication system allows us to retrieve the information we have saved at any time.
5. It is a cheaper communication system than any other communication system.
6. The error detection and error correction is very quick and easy in the digital communication system.
7. In the digital communication system, the input signal and the output signal are not much affected by the noise or interference.
8. The circuits used in the digital communication system are easy to design, more reliable and cheaper.
9. One can use similar devices for a large number of purposes in the digital communication system as many devices have the same encoding process.

Note:One can also explain the advantages of the digital communication system by considering different points of differentiation for explaining the advantages of digital communication system over the analog communication system (communication with the help of radio waves).
