Question

Differentiate between Analog and Digital communication. 

Answer 1

The signal (current or voltage) in the form of continuous, time-varying voltage or current are called continuous  or analogue signals. Shows a pulse waveform in which only discrete values of voltages are possible. It is  convenient to use binary mumbers to represent such signals. 

Answer 2

An analog communication system uses analog signals for the transfer of information whereas a digital communication system uses digital signals for the transfer of information. In analog communications, signals are consist of continuous values but in digital communications, signals are consist of discrete values.
