Why we shift from analog to digital?

The most important reason to make the switch to a digital signal is because it will free up valuable portions of the broadcast spectrum, which can then be used for other purposes, such as advanced wireless services and for public and safety services.

Why Digital communication is preferred over analog communication?

The Digital Communication’s main advantage is that it provides us added security to our information signal. The digital Communication system has more immunity to noise and external interference. Digital information can be saved and retrieved when necessary while it is not possible in analog.

What is digital and analog communication?

Analog communication uses analog signal whose amplitude varies continuously with time from 0 to 100. Digital communication uses digital signal whose amplitude is of two levels either Low i.e., 0 or either High i.e., 1. 03. It gets affected by noise highly during transmission through communication channel.

What is analog and digital communication?

Analog Communication. Digital Communication. Analog communication uses analog signals for the transmission of information. Digital communication uses digital signals for the transmission of information. Analog communication uses signals that can be represented by sine waves.
