### Problem sets

This page will be updated each week to list the homework assignments for that week. Unless otherwise specified, problems are from the end-of-chapter sections in Mitra (3rd edition).

# Date assigned Problems Date due Solutions
1 Wed 2015-05-27 2.2, 2.5 (a), (c), (e), (g), 2.7 (a), (b), (c), 2.12, 2.13, 2.31,
Matlab: M 2.3 (no need to repeat theoretical part from 2.31), M 2.4
(for this week, I have scanned in the questions)
Wed 2015-06-03
2 Wed 2015-06-03 2.41, 2.49, 2.52, 2.66 part (a) only.
