As I understand from references :-

start with positive site

but 1 means high to low

and 0 means low to high

low is 0 and high is 1

and when there is found of 0 inverse the next bits.

is it right?

We can represent Low voltage in two ways and high voltage in two ways as above .

So we draw two waveform for any data...

k got it

query: I do not get why you have draw two different encoding here in your first answer for differential manchester encoding while I know it is unambiguous.

See, there are 2 standards .

Forouzan along with William stallings book follow IEEE standards . Where Tanenbaum book follows G. E. Thomas standard .

It is just the convention which determine the correct answer.

see this from IIT KGP, they follow IEEE standard - http://nptel.ac.in/courses/Webcourse-contents/IIT%20Kharagpur/Computer%20networks/pdf/M2L4.pdf

and this one from IITB , they follow G E Thomas version --

and we generally follow IEEE standards.

see this gate question https://gateoverflow.in/3505/gate2007-it-61

In** IEEE standard ** *'1' is represented by low-to-high* and '0' represented by high-to-low .

And according to** G.E. Thomas' convention** *'1' by high-to-low transition * and '0' is expressed by a low-to-high transition .

@hem chandra

Read that gate question link , read 2 answers and all comments, i assure your all doubts related to differential Manchester will get cleared.

and **there is no term as Integral Manchester,** It was just put there in question to confuse students.

There is no such topic and term like Integral Manchester encoding . They put this into Gate question to confuse students.

For understanding differential manchester encoding see this thread and clealrly understand 2 given diagrams :
