Course Outcomes: After studying this course, students will be able to:

• Explain concept of Dependent & Independent Source, measure of information, Entropy, Rate of

Information and Order of a source

• Represent the information using Shannon Encoding, Shannon Fano, Prefix and Huffman Encoding


• Model the continuous and discrete communication channels using input, output and joint probabilities

• Determine a codeword comprising of the check bits computed using Linear Block codes, cyclic codes

& convolutional codes

• Design the encoding and decoding circuits for Linear Block codes, cyclic codes, convolutional codes,

BCH and Golay codes.

Question paper pattern:

• Examination will be conducted for 100 marks with question paper containing 10 full questions, each of

20 marks.

• Each full question can have a maximum of 4 sub questions.

• There will be 2 full questions from each module covering all the topics of the module.

• Students will have to answer 5 full questions, selecting one full question from each module.

• The total marks will be proportionally reduced to 60 marks as SEE marks is 60.
