a) Convert the following bitstream to signal using one scheme for each requirement: [6]

Data: 1 0 0 0 1 1 0 1 1 0 1 0 1 1 0 0 0 0 0 1

Requirements:

i) You can ignore: Self sDifferential Manchester solves a number of common problems that occur in signal encoding processes, what are they and how have they solved synchronization and DC component problem.

Keep in mind: Low bandwidth is required

ii) You can ignore: High bandwidth problem

Keep in mind: Self-synchronization is necessary and no DC component problem should exist.

iii) You should maintain a proper balance of bandwidth utilization and self-synchronization.

b) What is the advantage and disadvantage of using Block Coding signal encoding technique? Convert the Data given below into signal using 4B/5B block coding technique with MLT-3 line coding scheme. The table below shows the substitution of blocks. [6]

Data: 1 0 0 1 1 0 1 0 1 1 0 0
