Class Web Site - Announcements

Announcements:

I have posted the solutions to Assignment 6. They are accessible from the Assignments index page.

I have posted an online evaluation form for this web site. It is available in the Evaluation section or by clicking the hot link in the previous sentence. Please fill out the form, so that I can improve the web site for next year's students. Thanks.

99-11-17 I have posted Assignment 6. (Warren, did I get the link right this time? :-))

99-11-14 I have posted my responses to your questions and suggestions. Once again, I apologize for the delay. I hope that they are still of some benefit. I am a bit discouraged by some of the suggestions that could best be handled by raising the issue during class when I can give the page number or add some written comments that would address your concerns.

99-11-12 I have posted the solutions to Assn 4 in the Assignments section.

99-11-5 With regard to the EE 419 Lab on filters, I assumed that you had been introduced to frequency scaling, which is apparently not the case. Check your textbook from EE 223/EE 312. There should be a discussion about frequency scaling. You can also see the examples in the Course Notes. The approached used in the examples is to design the circuit for the normalized frequency and then scale the capacitor values to get the desired cut-off frequency.

99-11-3 I have included two new links on the Links page on active filters. These are at the end of the Technical Information section. The first one, from National Semiconductor is quite thorough. Should I include this in the Course Notes in the future?
I have posted Assignment 5 to confirm the instructions given in class. Note: I have been kind enough to include the hot links to standard component values that can also be found on the Links page. I forgot to mention in class that there are many software programs to help in filter design. One of these is FilterPro from Burr-Brown. It is available on the Engineering computer server under Electrical. However, it is freely available, if you want your own copy. See the Links page for the hot link.

99-10-28 I have posted the solutions to the midterm exam in the Assignments section.

99-10-22 I have posted the worked example on noise analysis in the Notes section. Have a good weekend, and I will see you on Monday for the midterm exam.

99-10-19 The solutions to Assignment 2 have been posted.
I have posted a point form description of the process used in working through the example of noise analysis of the noninverting amplifier. This is under the Notes section in the navigation panel on the left.

99-10-15 The figures for the solutions to Assignment 1 have been posted as a pdf file on the Assignments index page. Also the figures for Question 4 on Assignment 4 have been posted as a pdf file. I would appreciate any feedback that you want to offer with regard to this way of presenting figures (and potentially equations).
I have also posted my response to Round 2 of Questions and Answers.

99-10-14 FINALLY I have posted the solution for Assignment 1 (sort of). The figures are still not scanned and posted. Hopefully tomorrow.

99-10-13 I have added links for standard resistor and capacitor values to the links page.
Here is the link that I mentioned today on optical measurements. http://www.intl-light.com/handbook/ch07.html This deals with the geometry of solid angles as well as the concepts of radiometric and photometric measurements and units. You may also want to check Chp 10 on photodetectors and Chp 13 on radiometers. In the latter case, there is a good discussion of using integration to average noise. They also mention the need to chop the input signal.

99-10-05 On Assignment 1, one of you used thermocouple tables from Pyromation Inc. I was not familiar with this company, so I checked their website (http://www.pyromation.com/). They show some sensors that are manufactured for some very interesting applications. Under the Literature section there is a very good article on selecting temperature sensors. Only RTDs and thermocouples are discussed because that is all they manufacture. If you select Download, then you can get to a folder that has tables of values for a variety of RTDs as well as thermocouple tables.

99-09-29 My responses to your questions and suggestions have been posted. Use the Q&A link to get to Round 1 (and FAQs).

99-09-16 The Course Notes are in!!! I have this on reliable report from one of your colleagues. He knows who he is, and that he has collected a brownie point. :-)

99-09-13: Assignment 1 is now available in the Assignment section. You can get there by clicking on Assignments in the Navigation panel on the left. Assignment 1 is due Sept 22.

All assignments, solutions, notices, and extra class materials will be in this site.
