ELEC 101, Spring 1998
Prof. Rich Kozick

Homework 6

Date Assigned: Monday, February 16, 1998
Date Due: No problems are due, but see dates listed below.

  1. Exam 1: We will have Exam 1 on Wednesday, February 18. The topics will include all material covered in lecture, lab, and homework through today's class. The exam will be closed-book and closed-notes. An EE graduate student, Ligong Zheng, will administer the exam, since I will be in Washington, D.C. In order to guarantee fairness, I will instruct Ligong to not answer any questions during the exam. If an exam problem is not clear to you, do your best to explain any assumptions that you make in your answer.

  2. Lab this week: Please do the exercises in the "Digital-to-Analog Conversion" section of Lab 4. Include your circuit diagram and design procedure in your lab notebook. For the D/A converter based on Figure 13.37 in the text, please design the circuit, but you do not have to construct the circuit. In other words, you can omit item 2 in the list of activities.

    The main activity is to design and construct the 3-bit D/A converter based on the R-2R ladder approach in Figure 13.38. Each student should construct the circuit individually, as described on the Lab 4 assignment. Ligong Zheng will be in lab on Thursday morning and afternoon. Please demonstrate your circuit to him, and give him your lab notebook for grading. Proper operation of your D/A converter will be counted as a lab quiz grade. Guidelines for what you should include in your lab notebook are given on the course syllabus.

    Please complete your circuit before coming to lab. Then in lab, you can demonstrate your circuit and leave. Ligong can provide some help debugging your circuit. I ask you to please attend your assigned lab section (AM or PM), so that the lab does not become overcrowded in the afternoon.

  3. Reading for Friday, February 20: Section 2.5 on the Thevenin equivalent circuit.
Thank you.
