Difference between analog and digital signal in computer network
Answers
Hii mate!!
Differences b/w Analog signal and digital signal are following:
◆Basic
An analog signal is a continuous wave that changes over a time period.
A digital signal is a discrete wave that carries information in binary form.
◆Representation
An analog signal is represented by a sine wave.
A digital signal is represented by square waves.
◆Description
An analog signal is described by the amplitude, period or frequency, and phase.
A digital signal is described by bit rate and bit intervals.
◆Range
Analog signal has no fixed range.
Digital signal has a finite numbers i.e. 0 and 1.
◆Distortion
An analog signal is more prone to distortion.
A digital signal is less prone to distortion.
◆Transmit
An analog signal transmit data in the form of a wave.
A digital signal carries data in the binary form i.e. 0 nad 1.
◆Example
The human voice is the best example of an analog signal.
Signals used for transmission in a computer are the digital signal.
