Assignment 5
PULSE AMPLITUDE MODULATION
1 . Let fs = 2khz be the symbol rate . If 4 PAM signal samples are generated per symbol at what
intervals would you have to sample the o/p ?
2 . Why do we use pulse shaping?
3 . What is the effect of error in timing recovery?
4 . Draw an eye diagram and label it according to the information that it provides. Assume levels with 2 possible
values.
5 . How can an infinite interpolation sub filter be represented by a finite tap FIR filter.
6 . Why use a mailbox/buffer to write o/p samples? is it always needed?
7 . How can one be sure to stick to the symbol frequency while transmitting different samples in a symbol period.
