Old Items
This page contains an archive of announcements which appeared on
the main course page. The items are arranged chronologically
with the most recent items at the end.
- The textbook is now available at the UBC Bookstore.
- Due to a lack of space in the current lecture room no more
students will be allowed to register for the course unless a
larger classroom can be found or students currently registered
drop the course.
- Students who are not in the EE department should contact
Rob Ross
to get an account on the department's Unix system.
- The EE office has two copies of the Matlab documentation
which you may borrow for up to 2 days. You will be required to
leave a $50 deposit.
- Use the
PRINT
command to print your Matlab
plots (use HELP PRINT
for more information).
- The box for handing in your assignments is outside MCLD 410.
- How Assignment 1 was marked
- The bookstore says there are 4 copies of the textbook left
on the shelves. The EE section has apparently been moved so you
may have to look around. Another 8 books will be ordered from
the publisher. If you would like to be sure of getting a copy,
give me your name and I will forward it to the bookstore so that
a copy can be put aside for you when they come in. It should
take about a week to get the extra 8 books shipped in.
- Starting on Tuesday, February 6 the lectures on Tuesdays
only will be held in the MacMillan building in Room 166.
- To do question 5 on assignment 3 you may want to be aware of
the exp() and log10() functions.
- How Assignment 2 was marked
-
Suggestions from Mike
(your TA) about the way to write up your assignments.
- A (long) list of Matlab commands
you might useful.
- Documentation on a simple Pole/Zero
Editor.
- Assignment 4 is due February 6, not January 30.
- A useful command
for making copies of matlab commands
- Please let me know if you are having problems with any of
the following:
- viewing or downloading files using your (free) Netinfo
dial-in account
- downloading or printing course notes, solutions, etc. in the
file format for the printer or software you use at home
- setting up the MATLABPATH environment variable or accessing
the M-files or data files required to do the assignments
- If you are trying to download course files using Netinfo
remember that it is a two-step process. First you must download
the files to your Netinfo file space and then download them to
your PC using z-modem (or kermit).
- If you want to run the pez pole/zero editor elsewhere
(e.g. if you have Matlab at home or you use a machine in another
department) you can retrieve the required files in a zip-format
archive,
pez27.zip (about 72 kB).
- You can download a .login.local file that sets up the
MATLABPATH environment variable. This would over-write any
existing .login.local file. If you have already set up a
.login.local (you can check using ls -a), use
your favourite Unix text editor to modify it (pico is recommended
for beginners).
- If you were unable to complete an assignment due to illness
and submit a Statement of Illness form (UBC 95/96 Calendar, page
71) your mark for that assignment will be set equal to the
average of the remaining assignment marks. In all other
circumstances late assignments will be given a mark of 0.
- Corrections/Clarifications to Assignment 5:
- In Question 1(a) you should assume the sequences a and b
have different periods (3 and 2 respectively).
- I didn't think it was possible to do Question 1(c) because
the two FFTs have to be of the same length, implying the same
period for the two sequences. I said you did not have to answer
Question 1(c).
- However, it is possible to compute the circular
convolution or correlation if you extend the two sequences to a
length of their lowest common multiple (6 in this case). In this
case you can compute the circular convolution/correlation both
``by hand'' and using DFTs of length 6.
- How Assignment 3 was marked
- The mid-term exam will be held on Tuesday February 27 1995.
- The bookstore says that the extra shipment of textbooks has
been received.
- How Assignment 4 was marked
- If you cannot print your Matlab plots because the printers
are down you may copy the postscript files to a 3.5 inch disk
(see the mcopy command) and hand in the disk with your
assignment. This should only be a last resort because the TA
doesn't have time to print out everyone's plots. The Matlab
commands used to generate your plots can always be written out by
hand.
- A tutorial will be held on Thursday, February 22 at 1:30 pm
in MCLD 214. Solutions to the Mid-Term Review Assignment will be
handed out. The solutions will also be posted on the Web page on
Thursday.
- The only office hours before the mid-term exam will be on
Monday, February 26 at 12:30pm in MCLD 155.
- For the mid-term review assignment:
- For Question 2, you may assume the ADC quantization range is
+/- 3 volts.
- Plagiarism is not acceptable, even in the case of
assignments. While it is acceptable to compare results or ask
other students for help, it is not acceptable to copy someone
else's assignment. The possible penalties for plagiarism include
being given a mark of zero for all assignments.
- How Assignment 5 was marked
- I have received a copy of The Student Edition of Matlab
for Microsoft Windows from Prentice-Hall. If anyone would
like to install it on one of the department's PCs, please let me
know.
- How the mid-term exam was marked
- How Assignment 6 was marked
- The final exam is scheduled for Wednesday, April 17 at 7:00
PM in MacMillan 166. I agree that it is a lousy time to
schedule the exam.
- How Assignment 7 was marked (this
was the 6th assignment)
- How Assignment 8 was marked
- How Assignment 9 was marked
- The lms.m function for Assignment 10.
- Exam review questions (assignment 11)
- The final exam is scheduled for Wednesday, April 17 at 7:00
PM in MacMillan 166.
- How Assignment 10 was marked
- Please check your assignment and mid-term mark using the Web mark form. Report problems with
assignment marks to Mike,
problems with mid-term marks to me.
- Please let me know as soon as possible if you would like to
review your final exam. If your final mark is on the border
between two grades please note that you have already been bumped
up where this would be reasonable. See the explanation at the end
of your marks report for details.
- Unclaimed assignments are on top of the collection box
across from room 411.
