Class Goals
The goals of ECE 112, Introduction to Electrical and Computer Engineering are:
(1) to introduce basic concepts in Electrical and Computer Engineering in a integrated manner,
(2) to motivate basic concepts in the context of a simple student constructed robot, and
(3) to illustrate a logical way of thinking about problems and their solutions.
Lecture Topics - subject to change
- Electrons, Current, Voltage and basic definitions.
- Circuit elements and schematics.
- Resistors and Ohms law.
- Modeling circuits with voltage and current sources.
- Power calculations.
- Applying Kirchoff's Voltage and Current laws to analyze simple circuits.
- Analyzing basic circuits with the circuit simulator SPICE.
- Analyzing basic transistor and diode circuits.
- Understanding the operation of logic gates.
- Analysis of the Robot circuits.
Required Reading
There is no text book for this class. The notes for each class session are found in the syllabus.
Our class will roughly follow the order of the notes. Please read through the material
before the lecture. The lab procedure for the week will also be
posted in the syllabus as they are prepared.
Getting Class information
A mail reflector (or group, list) for the class will be established by the beginning of class.
This "mail group" is where you find information about homework assignments, changes in test dates
or times, changes in due dates, changes in test locations, etc. In other words, really
important stuff .
The mailgroup is how I communicate with you outside the classroom. It can also be used as an
interactive forum where you discuss homework problems and solutions. Such usage is encouraged.
You are welcome to discuss homework solutions or approaches to solving a problem.
Students who register early for ECE112 during the fall term are automatically given ENGR computing
accounts and are added to the class mail list. You will receive a notification from the list manager
when you are added to the list.
The name of the class list for ECE112 is: ece112-w06@engr.NOSPAM.edu This name is
case sensitive. Replace NOSPAM with orst.
Laboratory
What you will need for lab:
In the first lab session, you will pickup your robot kit. You must be enrolled to get the kit. If you need
tools, you can buy a took kit. Tool kits are $27. If you have the proper tools to build the kits, you do
not need to buy tools. Here are the tools you will need:
Tools needed
* Tool Box
* Flat Head Screw Driver
* Philips Head Screwdriver
* Wire Strippers
* Side (diagonal) Cutters
* Needle Nose Pliers
* Solder Sucker ( we supply the solder)
* Digital Multimeter (DMM)
* Alligator clips
* Eye Protection (glasses work too)
Soldering irons and solder are supplied in the lab. We will be using industrial quality irons to make learning
to solder as easy as possible.
If you have never soldered, don't worry. We will teach you. This is not a soldering class, but it is a
fundamental EE skill that everybody should be proficient with. Besides, its fairly easy to learn.
If you have all the tools and also a soldering iron, you are free to work on the robot kit at your residence.
All lab sections meet in DH302.
Lab Conduct
No food or drink is allowed in the lab. No horseplay is allowed. Take care of the lab equipment. We can have a
fun time if we act like mature adults.
Homework
Problem sets are assigned on a weekly basis as seen in the syllabus.
Homework assigned in week "n" will be collected Tuesday of week "n + 1"
in class. Selected problems from the problem sets will be graded on
a 0, 1, 2 basis. Your homework grades will be posted by Saturday 5pm of
week "n + 1". You will pick up your homework from one of your TAs in lab
during the week of "n + 2". This way you can ask them directly if you
have questions about grading. You may want to keep a xerox copy of your
homeowrk since it takes time to get them back to you. Also, do not use
spiral bound paper. I suggest you use the green "engineering pad" available
in the bookstore. Unorganized or sloppy work will be returned with a
grade of zero. Late homework is not accepted.
If you have a missing grade but neglect to tell anybody about it for more than
1 week after it should have been posted, it will be too late. In other words, you
have one week to complain about a missing grade. After that, its too late.
If you don't pick up your homework in lab, it will be held there for 1 week and then
discarded. If you don't care about it, why should we?
Across the top of each page put:
Lab Section # Homework # Name last 5 of student ID
Please write the question or show the original circuit, then show your solution.
Show all work. Zero credit will be given for wrong answers with no work shown.
I strongly encourage you to work all of the problems till you understand them.
Watching me do them on the blackboard will hardly teach you no thing.
The exam questions will be taken from the problem sets with minor changes.
The exams are constructed such that if you understand all the lecture
material, and can do all the homework without help, you will do well.
Homework solutions will be made available on a timely basis (as I can get them done) so you
can check your homework.
Here is a well done homework assignment and how it can look.
