Midterm Exam

Print this page

• The midterm exam will have two parts: a written exam and a hands-on lab exam.
• The Written Exam will have about 20 written problems and about 20 multiple-choice questions covering material that you've studied in Unit 1 through Unit 4. All problems will be similar to problems on Homework #1 through Homework #4, and all multiple-choice questions will be similar to questions from the textbook's True/False and Self-Test quizzes in Chapters 1 through 7.
• Lab Exam: Here are the things I may ask you to do on the lab exam:
  • On the breadboard and in Multisim, build circuits using logic gates, decoders, encoders, multiplexers, demultiplexers, and a 7493 IC (the chip you used in Lab 3).
  • Use a logic probe to obtain experimental truth tables for these circuits.
  • Convert between binary and hexadecimal well enough to get a time of 60 seconds or faster on the Binary-Hex Challenge Game. (You'll have as many tries at this as you want--you don't have to beat 60 seconds on your first try.)
• You will be allowed to use a calculator.
• Except as stated below, you will not be allowed to use books, computer, or notes:
  • You will be allowed to use one sheet of notes (no larger than 8.5" by 11"), written in your own hand, with writing on one side only.
  • For the lab exam, you will be allowed to use a TTL Data Book or the Internet to find IC datasheets.
• While I don't expect you to memorize the pin-outs of any ICs, you should be familiar with the operation of the following ICs:
  • Comparator: 7485
  • Decoders/Demultiplexers: 7442, 7447, 74138, 74139, 74154
  • Encoders: 74147, 74148
  • Multiplexers: 74150, 74151
  • Parity Generator/Checker: 74280
  • Latches and Flip-flops: 7474, 7475, 74LS76
