Announcements:
It may be helpful to review material from the
undergraduate junior level course on signals and systems:
ECE 301 Signals and Systems We will look at notes posted there, especially towards the beginning of the course.
Exam 2 Topics: Weeks 4-6 material at course web site. Chaps 6, 11. (see syllabus for relevant sections.)
(1) CTFT Properties/Pairs, (2) DTFT
Properties/Pairs, (3) CTFT-DTFT Relationship, (4) Signal
Reconstruction from Samples: Sampling Theory, Ideal D/A
Conversion, (5) Aliasing, (6) VIP Multirate Formulas: (a)
Zero-Inserts and (b) Decimation, (7) Digital Upsampling,
(8) Fractional Time-Shift Filters (Ideal), (9) Digital
Subbanding, (10) Single Sideband Modulation.
Matlab Hmwk #2: Due: Monday, Nov. 10. Take my code
for Single Sideband Modulation based Digital Subbanding for 4 signals below
and generalize it for 5 signals. We will provide the 5 signals to you,
as everyone's program will be run to make sure they work, i.e., play back
the correct 5 original signals. So you will need to upload your code
so that we can run it. You will also need to plot the phase of each of the
4 fractional time-shift filters, and the magnitude as well. ALSO: plot the "before" DTFT and "after" DTFT for each signal as in my code.
"Before" means DTFT of original signal. "After" means DTFT after each signal has been separated and restored back to
its original sampling rate (and centered back at omega =0). Put together all the plots in a brief report -- no need to write conclusions.

Exam 1 Material: Chaps 1,2 plus 3,4,5. I would recommend
prioritizing these sections from Chaps 3-5 in the
textbook: Chap 3: 3.2, 3.4.3, 3.5.3, 3.5.4; Chap 4: 4.2.3,
4.4; Chap 5: 5.2, 5.3, 5.4

It may be helpful to review material from the
undergraduate junior level course on signals and systems:
ECE 301 Signals and Systems We may occasionally look at
notes posted there, especially towards the beginning of
the course.
Your primary homework assignment is to solve my old
exams (posted below) without looking at the solutions in a
timed setting. You can look at the solutions before and
after attempting the exam, but it is important to work
through them without looking at the solution. A few
students have asked for homework problems out of the
textbook, but I think the best homework, in terms of
preparing for the exam, is to work through my old exams.
Some history and miscellaneous course information:
This course emphasizes applications of Digital Signal
Processing (DSP) in compact disc (CD) players, wireless
communictions including OFDM and CDMA, radar, and speech
processing. Professor Zoltowski has taught this course the
Fall of every year since 1990.

Help for Matlab Hmwk 1: SimpleCrossCorrEg.m ;
Use convolution to do cross-correlation : ryx = conv(y,x(end:-1:1)) and throw away the first first M-1
values of ryx (where M is the code length) since those
correspond to negative time-shifts and the problem only
asks you to plot for positive time-shifts.
-
- Matlab Hmwk #2: *NEW*: Friday, Nov. 7. Take my code
for Single Sideband Modulation based Digital Subbanding for 4 signals
and generalize it for 5 signals. We will provide the 5 signals to you,
as everyone's program will be run to make sure they work, i.e., play back
the correct 5 original signals. So you will need to upload your code
so that we can run it. You will also need to plot the phase of each of the
4 fractional time-shift filters, and the magnitude as well. More details to come.
