ELEC 320, Fall 2004
Prof. Rich Kozick
Date Assigned: Wednesday, September 15, 2004
Date Due: Friday, September 17 and Monday, September 20, 2004
Please continue to study Chapter 1 in the Lathi text.
We will begin studying Chapter 2 next week, so please begin reading
Sections 2.1 through 2.4.
The key concepts in these sections are impulse response
- Exam 1 will be on
Wednesday, September 22.
The exam will cover the topics that we used in
Lab 1 (frequency response, Bode plots, etc.)
and Chapter 1 in the Lathi text.
- Reports for Lab 1
will be due at 9 AM on
Friday, September 24.
Your reports are to be done individually,
and you should present your filter designs,
analyze the frequency response (including the derivation
of the cutoff frequency), and present your measured data on Bode
Your report should discuss how well you achieved each filter
That is, you should compare the measured gains and cutoff frequencies
with the specified values.
- Please solve the following
problems in Chapter 1 of the Lathi text, and submit your solutions on
Friday, September 17.
Problems 1.4-1, 1.4-4, 1.4-5, 1.4-7, 1.7-1, 1.7-2.
** You can redo Problems 1.7-1 and 1.7-2
and submit your solutions on Monday. **
For Monday, September 20, please do Problem 1.8-1 in the text, and
contains several interesting Java applets that illustrate
signals and systems concepts.
Please visit this web page, and check out the
System Properties link.
Focus on the Continuous-time systems for now.
The objective is to classify
whether systems are linear, time-invariant, causal, etc. by applying
various input signals and observing the system output signals.
Try as many of the systems as you would like. At minimum, classify
systems A and F, and submit your solution on Monday, September 20.
Do not worry about classifying the systems as stable,
since we have not discussed stability.
Make a note if you discover any
interesting systems other than A and F, so we can look at them in
The experiments will work fine if you apply only one input signal
at a time. Some useful signals to apply might be a unit step u(t), a
delayed step u(t-1), a scaled step 2*u(t), and a sine wave sin(t). You
can try others also, but these should get you started.
