6.16 Manchester Encoding Used in Computer Networks
{"Image DocumentName": "6.16 Manchester Encoding Used in Computer Networks", "Image ImageDescription": "A variation known as a Differential Manchester Encoding (also called a Conditional DePhase Encoding) uses relative transitions rather than absolute. the representation of a bit depends on the previous bit. Each bit time slot contains one or two transitions. A transition always occurs in the middle of the bit time. The logical value of the bit is represented by the presence or absence of a transition at the beginning of a bit time: logical 0 is represented by a transition. and logical 1 is represented by no transition. Figure 6.13b illustrates Differential Manchester Encoding. most important property of differential encoding arises from a practical consideration: the encoding works correctly even if the two wires carrying the signal are accidentally reversed. \u00a9 2009 Pearson Education Inc., Upper Saddle River, NJ.
