4. Advantages: Less expensive More reliable Easy to manipulate Flexible Compatibility with other digital systems Only digitized information can be transported through a noisy channel without degradation Integrated networks Disadvantages: 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 synchronized, whereas generally speaking this is not the case with analogue systems. Advantages: Uses less bandwidth More accurate Disadvantages: The effects of random noise can make signal loss and distortion impossible to recover
