What is digital communication?
Digital communication is the process of devices communicating information digitally. This tutorial helps the readers to get a good idea on how the signals are digitized and why digitization is needed.
What are the advantages of digital communication over analog communication?
As the signals are digitized, there are many advantages of digital communication over analog communication, such as − The effect of distortion, noise, and interference is much less in digital signals as they are less affected. Digital circuits are more reliable.
Why are digital signals used for long distance communication?
The conventional methods of communication used analog signals for long distance communications, which suffer from many losses such as distortion, interference, and other losses including security breach. In order to overcome these problems, the signals are digitized using different techniques.
