VIP: I will NOT have the Exam 3's graded in time to hand out in
class today. My apologies. They can be picked up tomorrow (Friday)
from Bonnie or Sherry in MSEE 330 during their normal working hours.
ALSO, my office hours this morning (Thursday) are moved due to
tomorrow.
We'll discuss in class today.
Final Exam scheduled for Monday, May 4, from 10:20 am to 12:20 pnm
in CL50 224. Final class on Thursday, April 30, will be review session
for Final Exam. Coverage is comprehensive. Same rules as previous
exams. See old Final Exams below (note: solutions for final exams are
not posted.)

Exam 3:
Exam 3 and Solution
to Exam 3. Exam 3 ran Thursday, April 23 in-class.
Exam 3 ran Thursday, April 23 in-class.
Coverage: Primarily Text Chapters 7 and 5, Homeworks 8-9.
Primary coverage topics: Sampling Theory and Discrete-Time Fourier
Transform, properties and pairs. Also, relationship between DTFT and
Fourier Transform when
the DT signal was obtained by sampling a CT (analog) signal. Also,
frequency response of DT LTI systems described by difference equations.
Working through my old exam 3's without looking at the solution
will help prepare you for our Exam 3 this semester.
*VIP* Homework 9 on Chap. 5 material (DTFT) was due Thurs.,
April 16: Homework 9 and Hwmk 9 Solution
Exam 2 ran Thursday, April 2 in-class.
*VIP* Please see email sent to everyone today (4/1) for some
clarifications
regarding Exam 2. Only a single handwritten two-sided crib sheet is
allowed for this exam, in addition to the textbook.
No calculators. A table of Fourier Transform properties
will be attached to the exam, with the j notation removed
and some additions (e.g. Duality property) relative to Table 4.1
in the textbook.
Coverage: Primarily Text Chapter 4, Homeworks 6-7.
The primary topic covered is the Fourier Transform, properties and
pairs. Working through my old exam 2's without looking at the solution
will help prepare you for our Exam 2 this semester.
*VIP* Homework 8 on Chap. 7 material (sampling theory) due Tues.,
March 31:
Homework 8 and Solution to Homework 8.
Fourier Transform Tables where units for frequency variable is
Hertz:

Prof. Zoltowski's weekly Office Hours are Tues/Thurs before
class from 11:30 am to 1 pm in MSEE 356.
Exam 1 from Spring 2009:
Exam 1 and
Solution to Exam 1. Mean=73.6, Std
dev=16, Median=76
*VIP* First Exam is Tuesday, Feb. 24 in-class: open book
plus one loose 8 1/2 x 11 handwritten sheet of paper.
Coverage: Text Chaps 1-3, Homeworks 1-5. Fourier Series
will be included on the exam as in my old Exam 1's posted below
along with solutions. You should try the old exams without
looking at the solution. (The 2008 exam did not include Fourier
Series.)
WEEKLY HELP SESSIONS: *VIP* weekly Tues at 7 pm in EE117 (1st help
session tonight, 1/20, in EE115)
TA OFFICE HOURS: Daniel Aguiar in MSEE 386H: MW 2:00-4:00 pm and
TTh 4:00-6:00 pm.
INSTRUCTOR OFFICE HOURS: Prof Zoltowski in MSEE 356: T Th 11:30 am
- 1 pm
NOTATION CHANGE: Notation-Revised Table 4.1 of Fourier
Transform Properties :
Notation-Revised Table 4.1 .
I removed the j factor notation in how the Fourier Transform is
written
in the text. The authors attempt to draw upon what you learned in
ECE202,
viewing the Fourier Transform as the Laplace Transform X(s) evaluated
along the imaginary axis s=j w . As we'll discuss in class, this can
be confusing. I will attach the revised table to each exam.

to frequency response of LTI systems described by difference equations.
