Digital Vs Analog ( Advantages & Disadvantages )

Definition of Digital
A method of storing, processing and transmitting information through the use of distinct electronic or optical pulses that represent the binary digits 0 and 1.

Advantages of Digital -

• Less expensive
• More reliable
• Easy to manipulate
• Flexible
• Compatibility with other digital systems
• Only digitised information can be transported through a noisy channel without degradation
• Integrated networks
  

Disadvantages of Digital -

• Sampling Error
• Digital communications require greater bandwidth than analogue to transmit the same information.
• The detection of digital signals requires the communications system to be synchronised, whereas generally speaking this is not the case with analogue systems.
  

Definition of Analogue
Analogue is a transmission standard that uses electrical impulses to emulate the audio waveform of sound. When you use a phone, the variations in your voice are transformed by a microphone into similar variations in an electrical signal and carried down the line to the exchange.

Advantages of Analogue -

• Uses less bandwidth
• More accurate

Disadvantages of Analogue -

• The effects of random noise can make signal loss and distortion impossible to recover
