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
