- Quiz 2:
We will have Quiz 2 on Wednesday, October 7.
The topics for the quiz include classifying systems
(linear and time-invariant), impulse response,
and convolution for discrete-time and continuous-time systems.
For practice with computing the convolution operation,
I would suggest that you work on
Homework 11, this homework assignment, and
- For Lab 3,
you can omit item 8 from the lab report.
We will discuss this item in class on Friday, October 9.
- We will not have lab on Thursday, October 8
in order to keep the Tuesday and Thursday sections from getting
too far apart.
(The Tuesday lab section will not meet on November 24 prior
to Thanksgiving break.)
- Listed below are some extra problems to give you more
practice with discrete time systems.
These do not have to be handed in, but I will answer questions
about these problems in class on Monday.
- Problem 3.2 in the text for practice with impulse
- Problem 3.5, parts (a) and (b) for convolution.
Remember that you can check your result with the
MATLAB command conv.
- A Java applet that graphically illustrates
convolution is available at
with the title
"Joy of Convolution".
I think that this exercise helps you to visualize the convolution
and I suggest that
you should check it out.
(Nothing needs to be handed in for this part.)
- Please perform the following
continuous-time convolution operations:
Problem 3.15 (all parts).
For case (c), the integral needs to be evaluated explicitly.
I suggest that you draw pictures in order to get the proper
limits on the integral.
Do your best on these problems, and we will review the solutions
- For more practice, try
Problem 3.19 (hint for part b: use linearity and time-invariance
with your answer from part a).
However, this does not need to be handed in.
