2 This Time Lecture Overview Logistics Discuss syllabus Class overview & logistics Content Prefixes Definitions: Current, Voltage, Power, & Energy Passive sign convention Circuit elements Ideal Sources J. McNames Portland State University ECE 221 Fall 2009 Lecture 1 2

3 Miscellaneous We do have laboratory meetings during the first week Parts kits available in the bookstore Recitation sections begin next week J. McNames Portland State University ECE 221 Fall 2009 Lecture 1 3

4 ECE 221 and ECE 201 These are listed as two separate classes, but you receive the SAME GRADE for both ECE 221 is 3 units and ECE 201 is 1 unit, for a total of 4 units Class ends at 11:20 am (or so), not at 11:50 am as listed in the class schedule The grading breakdown is listed in the syllabus (covered later) J. McNames Portland State University ECE 221 Fall 2009 Lecture 1 4

5 Archived Lectures Classes will be taped this term Will be posted on the web But slides available on the web in advance Uses Window s media player (and others?) Typically posted within 24 hours of lecture Can use in the CECS labs with head phones Very popular, especially with working students J. McNames Portland State University ECE 221 Fall 2009 Lecture 1 5

6 People Who Can Help Teaching assistants Xiao Li, Swetha Mettala Gilla, Vamsi Parasa, and? Office hours, contact information, and recitation sections to be posted on course web site My office hours M 11:30-12:30, T 8:00-9:00 FAB Private tutor (for pay) Memo, , vurkac@ece.pdx.edu J.

7 My Background Ph.D Teaching in PSU ECE dept. ten years Have taught this course many times Research area: Biomedical signal processing See J. McNames Portland State University ECE 221 Fall 2009 Lecture 1 7

8 Textbook Electric Circuits, 8th ed., by Nilsson & Riedel One of the mostly widely used across the US (and world?) Verbose Many examples Good homework problems Leading alternative: Alexander & Sadiku s Fundamentals of Electric Circuits, 3rd ed. Reasonably error-free, but please me if you find any errors J.

10 Lecture slides created fall 2000 Posted on the class web site Lecture Notes I will be updating them throughout the term Updates will not be drastic, so old notes should suffice in most cases Watch for updates as late as 9:30 am the day of the lecture Workspace is provided for examples that will be filled in during lecture Bring your calculators to help work out examples in class J. McNames Portland State University ECE 221 Fall 2009 Lecture 1 10

11 Homework & Online Lectures Homework solutions will be posted shortly after assigned Previous students have used the solutions as a learning tool Lectures will also be posted online J. McNames Portland State University ECE 221 Fall 2009 Lecture 1 11

12 Read Chapters 1 & 2 Homework Assignment 1 Problems Ch. 1: 3, 7, 10, 11, 15, 28, 30 Assignment posted on the class web site Solutions already posted Due on Monday, Oct. 5 In class or electronic file upload (scans, <5 MB) J. McNames Portland State University ECE 221 Fall 2009 Lecture 1 12

13 Strongly encouraged Scientific Calculators Recommended features Manipulate complex numbers Solve simultaneous linear equations Programmable Graphing (not critical) Favorites: TI 89, TI 92 Plus, TI Voyage 200 In particular, check out the EE*Pro application Can use during exams for ECE 221, but uncertain for ECE 222 and ECE 223 Bring to lectures Must learn to use on your own J. McNames Portland State University ECE 221 Fall 2009 Lecture 1 13

14 General Comments on Class Challenging Fast pace Relatively high rate of attrition Many new abstract concepts Lays the foundation for many ECE classes to follow Many critical concepts Mastery of these essential to succeed in EE or CPE programs J. McNames Portland State University ECE 221 Fall 2009 Lecture 1 14

15 Suggestions for Good Performance Attend TA s recitation sections Work through the practice problems More examples available in Schaum s Electric Circuits Ask questions Review lectures online Stay caught up Pay careful attention to exam topics Work through previous exams under time constraints before you look at solutions General rule: If you can solve the homework problems AND exam problems from previous terms, you ll do well on the exams J. McNames Portland State University ECE 221 Fall 2009 Lecture 1 15
