a- Explain how multilevel line encoding schemes work?
b- Use the multilevel 2B1Q line encoding scheme to draw the signal to be sent through the medium if the sequence of bits is: 1010010100110011.
Previous level: Previous level positive negative
Next bits 00 01 10 11
Next level +1
Next level -1 -3 +1 +3
-1 -3
Transition table
c- Draw your answer using IT tools (Microsoft Word, Paint, ...).
d- Discuss if the 2B1Q line encoding scheme is able to ensure: Self-synchronization, avoid baseline wandering, avoid DC component, ensure built-in error detection, Immunity to Noise and interference, and its complexity
