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.
