Assignment No. 2
Semester: Spring 2015
Data Communication - CS601
Total Marks: 16

Due Date: 08/06/2015

Objective:

To have the understanding of digital to digital encoding schemes.

How to develop assignment file:

• You are required to make assignment solution in hand written form and submit the colored scanned copy of the hand written assignment as image file or by copying the scanned image in word file.
• Assignment solution will also include handwritten student ID and name.
• You are required to use only blue ink to solve the assignment.

Evaluation criteria:

• Photo copy submitted assignments or solved in any other color except blue will be graded as zero.
• Assignment submitted without handwritten student ID and name will be graded as zero.
• If student submit assignment by copying image on word file then only hand written material will be assessed and any typed text will not be evaluated.
• After confirming the above criteria Assignment will be marked according to marking scheme.
• The assignment submitted after due date will be graded as zero.
• The submitted assignment does not open or file is corrupted will be graded as zero.
• Your assignment is copied from internet, handouts or from any other student will be graded as zero
(Strict disciplinary action will be taken in this case).

Please view the Assignment Submission Process document provided to you by the Virtual University for uploading assignments.

Assignment

Show the NRZ-I and Differential Manchester for the following bit pattern.

1 1 0 0 1 0 1 1

Assume that NRZ-I signal starts with negative polarity and for Differential Manchester assume first transition for 1 is Negative-to-Positive.

Provide your hand drawn solution showing bit transition with clock interval for both encoding schemes.

Wish You All The Best

Here's The Differential Manchester Encoding..
I'll Upload the NRZ-I Encoding in a short time.

hy huma can you guide me how you make this assignment.

So simple.. 
In Differential Manchester Encoding , Transition of a signal takes place only when the next bit is 0. For Ease, First you may draw lines where the next bit is zero then synchronize rest of the bits.

Where as in NRZ-I encoding The transition of a signal takes place only when the next bit is 1 . if it is not 1 the state of the signal will remain unchanged.

I hope you will now understand.. If it is still unclear..  Please consult handouts it is not much difficult.. Thankyou.. :) 

hi thanks for upload these things... could you please let me know about 2nd graph?how can u make it with 1 positive then 1 again negative then 0 negative too?

I had explained above in a comment ....

yes but in question of assignment it gives started from negative? so u started it from positive and my Differential Manchester chart is match with yours.. only asking about NRZ-I chart

please explain it 

thanks
