Exams and Grading
The final grade is determined as follows:
| Graded Homeworks | 10% |
| Midterm Exam | 40% |
| Final Exam | 50% |
| —————————- | ——- |
| Total | 100% |
Special Announcements
The solution to the last part of the last problem in HW 11 is wrong. Since we mention in the problem that we restrict the quantizer to be uniform the number of points in any interval is roughly \delta * 2^{-r}.
The class will take place in BC04 from now on.
HW3 is a graded exercise.
HW4 is a Matlab exercise, you are welcome to join us in INF1 at 10:00 am on Mar. 15.
HW6 is a Matlab exercise, you are welcome to join us in INF1 at 10:00 am on Mar. 29.
HW8 is a Matlab exercise, you are welcome to join us in INF1 at 10:00 am on Apr. 19.
The midterm is set for April 20 from 8:15-10:00 in CO1. You are allowed to bring one piece of A4 paper (inscribed on all 6 sides if you wish). No magnifying glasses,
pocket calculators, cell phones, books, formula collections.
HW9 is a graded exercise.
HW12 is a graded exercise.
You can pick up your HWs on 23rd in the afternoon from INR 141. Also you are welcome to ask any question before the exam.
For the final exam, you are allowed to bring one piece of A4 paper (inscribed on all 6 sides if you wish). No magnifying glasses,
pocket calculators, cell phones, books, formula collections.
Instructions for Graded Homeworks
We will have a few graded homeworks. These will be announced
and are collected exactly one week after they have been posted. It
is OK to discuss problems with your friends. But once you write
down a problem, you have to write it down in your own words.
If we find similarities of solutions beyond random, all involved
homeworks will receive 0 points. We will not investigate who copied from
whom.
