1. Projects: Remember that you will present and/or demonstrate your lab projects on Thursday, December 4 and Tuesday, December 9. Your presentation should convey the basic idea of your project to your classmates. A written report that describes your project and results will be due for all students on Tuesday, December 9. Each group should submit one report.

   *** MODIFCATION DECIDED IN CLASS ON MONDAY, DECEMBER 1: ***

   All groups will present on Tuesday, December 9.
   We may extend lab for an extra hour.

2. Reading: Sections 7.1 - 7.3 describe the forward and inverse Laplace transform operations. Section 7.4 describes the application of the Laplace transform to solving differential equations. Section 7.5 on the transfer function is very important. You should also look at Section 7.6.

   We will end the course with the same topic that began the course: analog filters. Sections 8.4 and 8.5 discuss frequency response and Bode plots. We will not consider all of the details in these sections, but you should read them. Section 8.6 discusses analog filters from the point of view of the s-plane. We will get an introduction to the design and construction of higher-order analog filters. Up to this point, we have considered primarily first-order filters.

3. Submit your solutions to the inverse Laplace transform problems on Homework 23 by Friday, December 5, 1997.

4. Check out the "Exploring the s-Plane" demonstration at
   http://spectrum.ece.jhu.edu/wjr/explore
   Notice how the locations of the transfer function "poles" of a linear, time-invariant system affect how the system responds to a unit step input signal. Your observations should agree with our discussion in class about the relation between the s-plane and time signals. Nothing needs to be handed in for this exercise.

Thank you.
