Where (in the sequence of subsystems within a communication system) does the line encoder used? Draw a block diagram. Write a sentence or two on what is in the other boxes.
What are the two broad parameters associated with an efficient line encoder? What is their relative importance and why? What are the
optimal versions of those parameters and why? What is HDB signaling?
What is intersymbol interference? What is the significance of the two Nyquist criteria in selecting the pulse shape for transmission?
What is differential encoding and what does it accomplish?
