ELEC 320, Fall 2006
Prof. Rich Kozick
Date Assigned: Wednesday, September 28, 2006
Date Due: Friday, October 6, 2006
Please continue to study Chapter 2 in the Lathi text.
We will begin by studying the impulse response and convolution
for the next few classes and in Lab 4 next week.
Then we will study zero-state response (ZSR), zero-input
response (ZIR), the total response, and related topics.
- Lab 2 from September 18 and 20
will not require any report.
The reports for Lab 3 will be due in your lab session
next week (October 2 or 4).
Each student should keep a copy of the computer program used in
Lab 3 because you will need to use it for
item 4 on this homework assignment.
- Please solve the following
problems in Chapter 2 of the Lathi text.
Problems 2.4-14, 2.4-15, and 2.4-16 (all parts).
There are 8 problems here to give you practice with convolution.
Do not use the convolution table for these problems.
- Please use your computer program from
Lab 3 to approximate the convolution problem
that we discussed in class on September 27 and 29.
That is, approximate u(t) * h(t) where u(t) is the unit step function
and h(t) is a rectangular pulse with amplitude 1 for 0 < t < 1 and 0
Run your program with different values of "delta t" and show the
effect on the "staircase" approximation of the output signal.
Please revisit the URL
and experiment with the Joy of Convolution applet.
You do not have to submit anything for this item, but try to use the
interactive tool to improve your understanding of convolution!
