Differential Manchester Encoding . closed

Question

In Differential Manchester, inversion in the middle of each bit is used for
synchronization. The encoding of a 0 is represented by the presence of a transition both at
the beginning and at the middle and 1 is represented by a transition only in the middle of
the bit period.

Can any one explain above lines using drawing diagrams?

Answer 1

in differential manchester encoding  if next bit same as current bit we will not invert .

if next bit is different from current bit then we will invert the waveform.

see these diagrams , you will understand clearly https://electronics.stackexchange.com/questions/142453/differential-manchester-encoding

can u tell what is meant by immediate transition and continues wave form pattern?

May be this is not the best way but i know it in this way see
Imagine you are making the waveform by hand every time you encounter a 0 immediately you have to move you hand as there is an immediate transition but if 1 is encountered you may smoothly continue the graph pattern no sharp irregularities..

For further insight you may refer section 4.3.2 of tannebaum
