Describe the phenomenon of aliasing caused by under sampling. How can aliasing be mitigated?
What are the advantages of digital communication over analog?
What is quantization noise? How can you reduce it?
Derive an expression for S/N for PCM assuming uniform quantization. How can non-uniform quantization help?
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? Give an example.
What is the role of an equalizer in a communication system? Explain.
Why is it necessary to extract timing from a received signal? How is this done? What is timing jitter?
Explain in detail how eye diagrams are used? What do they measure and how?
How is PSK similar to DSB-SC?
Plot the PSD of ASK, PSK and FSK? Which takes up the most bandwidth and why?
From SNR point of view which is superior, PM or FM?
