I forget... ;-) [12/12]
Final grades should be available by Tuesday morning 12/14. [12/11]
The emphasis of the second exam will be from digital logic through op amps. This includes Chapters 12, 13, and 14 and the classes from Oct. 12 through Nov. 16.
However, as with most science and engineering courses, you should be ready to use the concepts introduced earlier in the semester as needed. [12/1]
Sorry, I cannot move the exam later. It is scheduled for the next to last meeting of our class. Since the MATH course actually has three class meetings remaining after its exam, perhaps its exam can be moved. [11/28]
I was wondering if there is anyway to post more hints or discuss or even extend the due date of this homework assignment past Wednesday. I know of several students including myself who have been having difficulty completeing this. Many of us have gotten nothing. It has been especially difficult since this week is crunch time--we all have an exam tomorrow as well as other homework assignments. Thank you for your time and consideration. [10/22 1:20pm]
I understand the time crunch you are facing; however, I am reluctant to extend the due date further. When you return from Thanksgiving break, I would prefer that you be spending time reviewing and preparing for the upcoming midterm exam rather than catching up on the homework. Turn in the homework by Wednesday before you leave and enjoy the holiday, rather than worrying about your pending homework assignments. Also, it is likely that I will be doing at least one (or maybe even two) of the homework problems in class on Tuesday before break, so make sure you attend class! [10/23]
The midterm exam is scheduled for Thursday, December 2. There is no other time to schedule it; I would not like to offer the exam on Tuesday, Nov. 30 since it is immediately after the Thanksgiving break. Nor would I like to offer it the last day of class on Tuesday, Dec. 7. [I am required to hold exams during normal scheduled class offerings.] Also, remember that our final exam is Friday 12/10 at 10:30am. [10/23]
No, I am not able to provide you with an activation code. Sorry. [10/8]
Traditionally I have compromised on this issue. For PHYS345, I permit a 3"x5" notecard for the final exam. In PHYS208, I provide a simple formula sheet since that course is more heavily invested in a myriad of formulas. However I truly believe, although you may respectfully disagree, that this course is not driven by many formulas. I have structured your exercises in the laboratory, in homework, and in the quizzes so that you have experienced enough work with the course material so that the few equations that you need should be fairly well ingrained at this point. Often a false security comes when the availability of a notecard is announced in a course, subverting active engagement with the material in a steady and deliberate pace. [10/27 5:20pm PST]
Yes, I was thinking in that direction too. I will probably try to develop a lab exercise using circuit simulation using Electronics Workbench combined with construction and testing of a real filter. [10/22]
OK, how about something like this: [10/20]
Sure, if I forget, just remind me! [10/20]
OK, I plan to do so. [10/14]
As you know, we have two weeks before the exam, which will cover the material prior to the class of 10/12. I think that should allow adequate time to "catch up." One way to fix the gaps in understanding is to figure out what you do know and what you do not yet know. As you have mentioned, this is probably best done during an office hour. If the office hours are not convenient (and can sometimes be full of interuptions anyways) suggest a time or two that would be convenient and I will see if my schedule is free then.
I contacted some of the best students from PHYS345 last year to see if they were interested, but it seems that they are busy with their own studies and other activities. Finding a capable EE major for a tutor would also be a possibility, but I am concerned that they would not be familiar with the scope of our survey course, and could make matters worse. Similary, our physics students typically do not have a circuits course like PHYS345 and will not know many of the analysis tools that we use. In short, I am not able to recommend a tutor for the course...
The beginning of this week is very busy for us. Do you think it would be possible to push back the due of the homework until thursday so that I would have time to actually do a good job on it. I am afraid that if it is due tuesday I will get tied up with studying for my mechanics of solids test that I will not be able to allow ample time to complete the homework. Thank you for your consideration. [10/10 11:40pm]
Can we possibly move the due date for this homework to Thursday of this week. I have worked on it and havent gotten a single one. I want to spend more time, but i have a solids test and a statistics test too!! Thanks so much for considering!!! [10/10 11:42pm]
I'm having a really tough time attempting to do the homework. I'm also struggling to try to study for my mechanics of solids exam on tuesday. If there is any chance you could push the homework due date back, I'd greatly appreciate it. [10/10 11:48pm]
I have been having a lot of trouble with the latest homework assignment. I have talked with several other members of the class and they have not gotten anywhere on the homework either. I have worked in excess of two hours on only the three problems from chapter 6 and have not gotten answers to either three. Neither have the other members of the class. We also have a rather large exam in a class on Tuesday. I personally was wondering if there was any way to delay the due date of this assignment. Thank you for your consideration. [10/11 7:13am]
When is the latest that the homework may be turned in for full credit? [10/11 1:55pm]
A number of us have worked on the problems, but haven't gotten anywhere. We've skimmed through the chapter, used our notes, and the hints that you provided, but we still can't work the problems. In addition, we have a Mechanics of Solids test tomorrow, Tuesday Oct. 12. We were hoping that you could give us an extension on the due date of the homework; preferably on thursday which allows another class and a review session. We'll appreciate any leniancy you can provide. [10/11 1:29 pm]
Delay homework due tomorrow. Most of us have two exams, two labs and three homeworks happening in the beginning half of the week. An extra day, possibly allowing the homework to be due at the discussion session would be greatly apprecitated. Also the extra day would clear up a lot of questions some of us are having with the homework. Thank you. [10/11 1:56pm]
I have no problem extending the deadline for homework until Wed. evening. But I would like to have a quiz on Transients in RC and LR Circuits on Thursday. That means that I would like to discuss that material at the review session on Wednesday evening. So I cannot extend the homework submission until Thursday.
I don't want to generate a backlog of work and topics by delaying your mastery of these recent subjects. We are rapidly approaching the study of digital systems, so there may soon be a brief respite for you. Sounds like Friday's Fall Break was not long enough... [10/11]
I agree that Electronics Workbench is an effective and easy-to-use tool for circuit simulation. You can probably understand why I held back its introduction until you were firmly grounded with circuit analysis techniques. It would be interesting to consider using it in an exam situation, but it won't be possible this year unless everyone brings a laptop to Gore Hall (a distinct possibility in future years!). I am considering the possibility of a lab practical exam at the end of the year; it could include a circuit or two for EWB... [10/7]
I was wondering if there was any possible way to move the review session from the sunday before the test. Thank you. [10/6 12:44am]
Unfortunately the only evening that I am available the week of the exam is Sunday. Sorry, but it must be Sunday evening... [10/6]
OK, I'll see what I can do. [10/6]
Thanks for the inquiry. I hope my discussion of the circuit during class today was helpful. [10/5]
Glad to hear that you are comfortable with the complex algebra. As you say, I was beginning to worry. I will spend some time in class on Tuesday giving the overview of where we have been, where we are going, and why, as well as tying up some loose ends. [10/3]
You have a choice between Tuesday 10/26 and Thursday 10/28 for reasons that I will explain in class. If your classmates are in agreement, I can reschedule the exam for Tuesday. We will discuss further in class... [9/30]
Update: As discussed in class on 10/5, there does not seem to be a conflict. We will keep the exam as originally scheduled for 10/28. [10/5]
After discussion with Mr. Xiang, following suggestions from several students, we have decided to make labs due in the drop box by Monday at noon. This should give you as much time as needed to work on the lab exercise and write your report and still give enough time for the reports to be graded and returned at the following week's session. [9/29]
I prefer to think of knowledge as a tool rather than a weapon. ;-) However I hear what you are suggesting and I plan on working through one or two detailed examples in class on Sept. 30. [9/29]
Try moving further from the wall... Seriously, remember that for the current through a section of a circuit to be in phase with the voltage across that section of the circuit, the net reactance in that part of the circuit must be zero. [9/27]
I have been working on the Physics homework for quite a while now and I am having difficulty understanding how to work out problems which have impedance in parallel. If you could give me direction as to how I should do this by pointing out where in your notes or in the book that I could find this, or just briefly explain, I would highly appreciate it. Thank you for your time. [9/27]
I have added a detailed numerical example of two reactive branches in parallel to Class 7. I hope you find this to be of help. [9/27]
One thing is that the ac circuit analysis homework, etc. will give you a chance to review the dc circuit concepts.
For the quizzes, I would recommend taking last year's quiz as a diagnostic the evening before this semester's quiz. Don't look at the posted solution until after you do as best as you can on your own.
Finally, during office hours, I can observe a student's circuit analysis process while working on a new circuit. Sometimes I notice a misconception or something that can be modified. [9/25]
Yes, there will be a quiz on nodal/mesh analysis on Tuesday 9/21 and one on Thevenin generators on Thursday 9/23. [9/19]
Yes, most definitely! That's the nice thing about web-based documents -- it is so easy to copy-and-paste. It would be a good idea to give attribution to the source -- you may also edit my drawings as you see fit for use in your lab reports. [9/14]
Let me remark on office hours anyways. My regularly scheduled hours are Monday and Tuesday 1:30-2:30pm and Wednesday evening 7:00-8:00pm. However if you find that your schedule prohibits you from meeting me during the regular hours, you may e-mail me for an appointment at a mutually convenient time. [9/10]
