Electronic Instrumentation (ENGR-4300)

Active Announcements Are Marked In Red For Emphasis

(April 25) Quiz 4: These questions are taken primarily from Experiments 9 and 10 and Chapters 6 and 7 of Gingrich. Be sure that you review this material thoroughly. This list might change a little, so check back. A copy of Quiz 4 from Fall 1998 is available for reference. A solution for Quiz 4 from Fall 1998 is also available. An additional quiz from another semester may also be added.

1. Combinational Logic -- You can be asked a problem like the one in Gingrich problem 4 on page 156. This problem is a classic example of using digital logic devices to control some piece of apparatus. You might have some optical sensors that produce HIGH and LOW signals depending on whether they sense some object. With 2 or 3 sensors, you can have a variety of inputs in a variety of sequences. If a particular sequence of events occurs, then you would want to turn something ON or OFF as a response. Thus, your system would be expected to obey some kind of truth table. You could be asked to identify which of several choices is the configuration of logical devices that would produce the desired truth table. The devices you will be expected to understand are found in sections 7.3 and 7.4 of Gingrich.
2. Digital Meets Analog -- A summing amplifier configuration (see figure 6.8 of Gingrich) can be used to convert a digital signal into an analog signal. There are two examples of such digital-to-analog convertors (DAC) in the Engineering Sciences 27 webpage at Dartmouth. There is also a short discussion of DACs available that uses PSpice simulations. You may be asked to convert a 3 or 4 digit binary number to an analog number. Remember that the binary number will be represented as ones and zeros but the voltage for a one is 5volts with TTL devices. We have not addressed this kind of device directly in a class assignment. However, it is a simple application of op-amps to digital circuits.
3. Schmitt Triggers vs Inverters -- At the bottom of page 3 of Experiment 10 is a PSpice configuration that is to show how Schmitt Triggers do not trigger several times near their turnon threshold, even with noise. The last figure of Part C (page 6) shows the experiment you were to do to show that Schmitt Triggers and inverters do not trigger the same. You may be given examples of figures taken from scope traces or PSpice simulations for each of these two cases and be asked to identify which is for the Schmitt Trigger and which is for the inverter.
4. Flip Flop -- For the Flip Flop simulation and experiment (Part D of Exp 10), you might be given several plots showing either simulated output or data from an experiment and be asked to determine what is connected to each of the inputs.
5. Misc. Experiments -- Given any of the Pspice or hardware configurations in experiments 9 and 10, you should be able to identify which input/output signal pair goes with which circuit. You should also know the properties of any of the devices used in these experiments.

(March 31) Your next easy chance for extra credit is the Vollmer Fries Lecture next Monday at 4pm in DCC 308. Check the Vollmer Fries website and our seminars website for further info.

I promise that the food is good and that you don't want to miss the opportunity to hear from a recipient of the MacArthur Foundation Fellowship. This award is also called the MacArthur genius award, since it is awarded to young scientists, writers, etc. who are already recognized as geniuses. Since next week is project week, your schedule should be flexible enough to take advantage of this great opportunity.

(March 27) Possible Quiz 3 Questions (Not all will be included). These questions are taken from Experiments 6-9 and Project 2. Make sure that you understand the basic work done in each of these experiments and project. The actual questions will be variations of what is listed below. A copy of Quiz 3 from last year and Quiz 3 from last semester are available for reference.

1. Approximately reproduce or identify the plots asked for in the PSpice simulations of Experiment 6 involving diode voltage regulation or Zener diode voltage regulation. Note that both DC sweep and transient analysis were asked for.
2. Any question included in a Results and Discussion section.
3. Old Homework #4.
4. Identify the types of op-amp configurations we have seen thus far.In addition, you might be asked to figure out what some configurations do that we have not yet seen. The latter questions will be multiple choice and not worth a lot. However, you might glance through the reading in Gingrich that covers op amps.
5. Given a copy of the basic receiver and transmitter circuit diagrams from Project 2, identify the function of each section or stage of the circuits. There will be a list of possible answers to choose from with at least two more answers than questions.
6. Inductance Measurement -- In Exp 9 you did a simple experiment to find the magnitude of an unknown inductance. You may be given data from another method, in the form of scope traces or simulated output, and be asked to estimate the inductance from this information. The circuit configuration to be used will be a series RLC combination. You may also be given some dimensions for the unknown inductor and be asked to estimate its inductance from an ideal formula. You should know whether or not this ideal formula will over estimate or under estimate the inductance of the coil.
7. Integrators and Differentiators -- Given a particular input signal, determine which output signal corresponds to a specific differentiator or integrator op amp configuration.
8. Transformers -- Given a resistive load connected to a realistic source using a transformer, determine when or whether or not the transformer is working as an ideal transformer. It is also possible to ask this question in a form similar to the previous question.

(March 15) Project 2: I apologize for a problem many of you had getting this project to work. Many of you had difficulties getting your receiver to work well because you used too large a bias resistor for the phototransistor. The basic circuit diagram (taken from the book The Laser Cookbook usually works just fine even though this resistor (the 200k) should be about 10 times smaller. The large value was chosen by the designer (I think) to protect the transistor. However, the phototransistors we got in our kits this year really need a bias resistor that is about 10 times smaller. With the larger resistor, there is not enough current passing through the transistor to fully turn it on. I should have had you investigate this phenomenon in Experiment 7 so that you would have known to try a different resistor here to see if your signal level improved. With the reduced signal levels you detected with your phototransistors, your circuits became much more sensitive to noise. Please be assured that this problem will be taken into account when grading your reports. Also, we will revisit this problem in a subsequent experiment when we learn a bit more about how transistors work.

(March 9) The last four practical quizzes are now available.

(March 6) In past semesters, each project required two reports -- a Pre-Project Report and a Final Report. Projects now require only a final report, unless the project description indicates otherwise.

(Feb 23) Here are the questions that could be included on next Monday's quiz (Only some of these will be selected). Please recall (see syllabus) that for any test, you can use one formula sheet, but no other reference materials. Note that you will also need to recall some of the more important topics covered in Quiz 1 (voltage divider, bridge circuits, Thevenin equivalents, ...). Quiz 2, from fall 1998 and Quiz 2 from fall 1999 are available as study guides.

1. In homework #2, you analyzed a series RLC circuit. On the quiz, you will be asked to consider such a circuit or part of a simpler circuit. You will either be given an RLC, RC, CR, RL, or LR circuit. You will be asked to find the voltage across the last element in the circuit if it is driven by a sinusoidal source. Your answer will require both the magnitude and phase of the voltage. The method is the same as in HW #2, but there may be only two impedances.
2. Convert the result of the first question (or a similar expression) from phasor form to real sinusoidal form.
3. Given one of the combinations listed in the first question above, identify whether it is a low pass filter, a high pass filter, a band pass filter or a band reject filter.
4. Given a list of standard resistors, capacitors and inductors, choose a combination that will allow an audio signal to pass but will filter out electrical signals produced by mechanical vibrations (like we saw with the cantilever beam) and 60 Hz line noise. You could also be asked to select components that would pass the mechanical signal, but reject the audio signal.
5. Given a simple circuit, set up the differential equation and initial conditions for voltage or current and then identify the solution from among 3 or 4 voltage and/or current plots. This question is, in effect, the transient form of the first question above, except that you do not have to figure out the solution yourself.
6. Given a particular diode rectifier circuit (half-wave or full-wave) and four possible oscilloscope images, select the scope image that would be observed across the output of the rectifier. This is the topic of HW#3. If you do this homework problem, you will be well prepared for this question. Since a question like this has appeared on Quiz 2 in each of the last three semesters, there is a good chance it will appear again.
7. Determine the gain of one of the three operational amplifier configurations we have studied: inverting, non-inverting and differential. Ideal conditions will be assumed.
8. Given any of the circuits you have simulated in experiments 4 - 6, identify which of several choices is the correct voltage or current signal at some point. You could also be asked to explain what information is contained in the figure. This questions could be in the form of a list of possible comments from which you will choose those that are true.
9. Given a simple mechanical oscillator or an equivalent simple circuit, determine its natural resonant frequency. You might be given a description of either device or a plot of their response vs. time.
10. There may be one more question, so watch this space.
11. The quiz will last no more than one hour.

(Feb 18) We now have started posting solutions to quizzes and homework on class reserves. Click on the menu item at the top of the syllabus page to access these materials.

(Feb 11) The first two practical quizzes are now available. Please check the Graded Work section of the syllabus.

(Feb 11) Open shop times will change next week. The times on Tuesday from 2-6 and Thursday from 12-2 are cancelled, since almost no one was able to make them. New open shop times will be announced on Tuesday, but there will probably be open shop Monday night from 8-10pm. Watch this space for further info.

(Feb 10) Quiz 1 Grade Distribution: A:90-100, B:80-89, C:70-79, D:60-69

(Feb 10) Extra Credit: From time-to-time, I will recommend certain seminars that should be of interest to you and also understandable. (Most seminars at universities are intended for grad students and faculty and, thus, are difficult for undergrads to follow.) If you attend the seminars I recommend, you will earn extra credit points if you email me (Prof. Connor) a few comments on the presentation. For students who cannot attend these seminars due to their class schedules, there will be other opportunities for extra credit. Detailed info on the first seminar is available.

(Jan 27) Open shop on 31 March (10-12 in the morning) has been cancelled. This is not a day where anyone should need extra time, since it is a quiz day and the first day of a project.

(Jan 27) Here are the questions that could be included on Wednesday's (2 Feb) quiz (Only some of these will be selected). Quiz 1, from fall 1998 is available as a reference. The questions for this sample quiz were generated with an older version of PSpice, so they look a little different.

1. Reduce a series or parallel combination of resistors to a single resistance.
2. Find the voltage across a resistor in a voltage divider configuration.
3. Find the voltage across a resistor in a voltage divider configuration with a load resistor attached.
4. Find the Thevenin equivalent of a voltage divider or a Wheatstone Bridge configuration.
5. Given an exact image produced on the oscilloscope, determine the mathematical representation of the signal displayed. For example, given a sine wave, find the frequency, the peak-to-peak amplitude, the rms amplitude, and/or the phase. A decaying sinusoid, like the ones observed in Experiments 2 and 3, is also a possibility.
6. Be able to answer the questions: Is an inductor a short circuit or open circuit at very low or very high frequencies? Is a capacitor a short circuit or open circuit at very low or very high frequencies? (Hint: think of high-pass or low-pass filters).
7. Given an image of one of the instruments we have used in this class (function generator, digital multimeter, scope, dc supply), identify the buttons you would push for some specified purpose. Only the most basic functions will be considered. This question will definitely be on the quiz, since every quiz should have a gift on it.
8. Given a PSpice Probe plot with two or more time-varying signals on it, identify which points in a circuit (also given) correspond to which signals.
9. Given a PSpice Probe plot with time-varying signals on it, show that the signals satisfy the appropriate voltage and current relationships.
10. Given that you wish to obtain a particular AC Sweep, DC Sweep, or Transient analysis with PSpice, describe the specific steps you would follow. You will be given blank windows and asked which ones you will use and what numbers you will input.
11. A few more questions may be added in the next day or so.
Note that these are all questions motivated by our experimental work. It will be a good idea to review the first two chapters of Gingrich's notes and the writeups for the experiments we have done. Also note that the circuits in these problems will be taken from the experiments.

(Jan 10) Please note that the grading scheme has changed a bit since last semester and since the first experiment was written up. It is now correct on the Syllabus. The only significant changes are that the experiments are now a slightly larger part of the overall course grade and the participation grades have been absorbed into the experiment and project grades.

(Jan 3) There is something added to the computers last semester that each of you should try, especially if you do not have much experience with the 'scopes, function generators and multimeters we use. When you click on Programs, the top item you should see on the list is called Hewlett-Packard Instruments. Select the top item from that list (also called Hewlett-Packard Instruments) and you will have access to two very nice instrument simulators that will permit you to learn how the work without worrying about breaking anything. If you wish to have these emulators on your home computer, you can download them from the HP Educator's Corner. The specific software you will need is called the Basic Instruments Emulator.

(Jan 3) Those of you who have access to a computer outside of class can obtain a copy of the OrCAD demo disk, which contains somewhat smaller versions of the software we use for circuit analysis. Go to the OrCAD webpage, click on the Free OrCAD Software Starter Kit and follow the directions to get your free CD.

(Jan 3) The class notes and Radio Shack pamphlets can be purchased for $10 from Audrey Hayner in JEC 6003. The parts kits will also be available from her or in class when they arrive later this week. A message will be posted when they are available. The price for the kits will be $50.
