1 votes 1 votes 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?

Can u tell in which corresponds which we use? 0 votes 0 votes Deepak Kumar 12 commented Jul 23, 2017 reply Follow Share 0 is represented by 1 is represented by So I draw two encoding scheme. 0 votes 0 votes hem chandra joshi commented Jul 23, 2017 reply Follow Share buddy i want to know why there is two different ones for this? and 0 has two representation and similarly for 1 can u explain how are u drawing the digital signal in above ones and in which condition we should use which one? 0 votes 0 votes Bikram commented Jul 23, 2017 reply Follow Share in differential manchester encoding if next bit same as current bit we will not invert . if it is different then we will invert the waveform. 1 votes 1 votes Please log in or register to add a comment.
0 votes 0 votes 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 -- https://www.cse.iitb.ac.in/synerg/lib/exe/fetch.php?media=public:courses:cs348-spring08:slides:topic03-phy-encoding.pdf and we generally follow IEEE standards. see this gate question https://gateoverflow.in/3505/gate2007-it-61 Bikram answered Jul 23, 2017 Bikram comment Share Follow See all 4 Comments See all 4 4 Comments reply Bikram commented Jul 23, 2017 reply Follow Share 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 . 1 votes 1 votes hem chandra joshi commented Jul 23, 2017 reply Follow Share sir what about the integral manchester encoding . is it same in Mr. Thomas and IEEE format? 0 votes 0 votes Bikram commented Jul 23, 2017 i edited by Bikram Jul 23, 2017 reply Follow Share @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. 0 votes 0 votes Bikram commented Jul 23, 2017 reply Follow Share There is no such topic and term like Integral Manchester encoding . They put this into Gate question to confuse students.
