Dan O. Popa, Intro to EE, Freshman Seminar Spring 2015 Assignments Assignments: –Homework assignments, which are necessary in order to understand concepts discussed in class.There will be 8 homeworks. –The course is closely coupled with EE 1106, in which there will be lab sessions in NH 129B. It may help those of you taking EE 105 and 1106 concurrently. –Reading Assignments: The assigned reading material will help you better understand the concepts. Materials from the reading assignments may also be part of course exams. –Examinations: One take home exam (midterm paper), one in class midterm (Scantron), and one in-class final exam (Scantron). –In rare circumstances (medical emergencies, for instance) exams may be retaken and assignments can be resubmitted without penalty. –Missed deadlines for assignments: Maximum grade drops 25% per late day (every 24 hours late). –All assignments are posted on course website, and will be due electronically on Blackboard. Midterm exams will be returned in printed form, but other assignments will be graded but not returned. Please check the answer key for justification of your grade.
Dan O. Popa, Intro to EE, Freshman Seminar Spring 2015 Honor Code Academic Dishonesty will not be tolerated. All homeworks and exams are individual assignments. Discussing homework assignments with your classmates is encouraged, but the turned-in work must be yours. Discussing exams with classmates is not allowed. Your homeworks will be carefully scrutinized to ensure a fair grade for everyone. Random quizzes on turned-in work: Students might be required to answer quizzes in person at least once during the semester for homework and lab reports. You may receive invitations to stop by during office hours. Credit for turned in work may be rescinded for lack of familiarity with your submissions. Attendance and Drop Policy: Attendance is mandatory in order to get full credit for class participation. If you skip classes, you will find the homework and exams much more difficult. Assignments, lecture notes, and other materials are going to be posted here, however, due to the pace of the lectures, copying someone else's notes may be an unreliable way of making up an absence. You are responsible for all material covered in class regardless of absences.
Dan O. Popa, Intro to EE, Freshman Seminar Spring 2015 Course Objectives 1.This is an introductory electrical engineering course. It presents a broad overview of EE, and focuses on fundamentals intellectual themes such as modularity, abstraction, and modeling. 2.The course material is divided between several areas offering an introduction to: 1.Intellectual themes of EE and what EE's do 2.Fields of study in EE 3.Basic resistive circuit concepts 4.Exposure to dynamic and electronic circuit elements 5.Introduction to signals and systems
Dan O. Popa, Intro to EE, Freshman Seminar Spring 2015 ABET Outcomes (a) an ability to apply knowledge of mathematics, science, and engineering This is a strong component of EE 1105, assessed through homeworks and exams. (c) an ability to design a system, component, or process to meet desired needs EE 1105 provides limited exposure to this topic, assessed through homeworks. (g) an ability to communicate effectively EE 1105 provides limited exposure to this topic assessed through exams and homeworks. (j) a knowledge of contemporary issues EE 1105 provides moderate exposure to this topic assessed through awareness of research fields in EE via exam questions.
Dan O. Popa, Intro to EE, Freshman Seminar Spring 2015 Student Learning Outcomes Students will acquire significant insight into: 1.Understanding of the EE main intellectual themes: modularity, abstraction and modeling through device, circuit and system examples 2.Understanding of EE specific block diagrams and apply algebra to solve basic network equations for resistive circuit elements. 3.Familiarity with contemporary issues and disciplines within EE.

Dan O. Popa, Intro to EE, Freshman Seminar Spring 2015 Intellectual Themes of EE Modularity (ex: device) –Manage complexity by reusing simple components (electrical, mechanical or code) nomenclature: devices Abstraction (ex: circuit, system) –Represent complex systems by connecting modules using interconnects Block diagrams, Data flow diagrams (state machines), signal flow graphs, electric circuits Modeling (ex: electronic vs electric) –Represent behavior of systems using mathematical abstractions
Dan O. Popa, Intro to EE, Freshman Seminar Spring 2015 Systems and System Models System = entity where inputs combine to produce an output. Building mathematical models based on observed data, or other insight for the system. –Parametric models (analytical): ODE, PDE –Non-parametric models: ex: graphical models - plots, or look-up tables. –Mental models – Ex. Driving a car and using the cause-effect knowledge –Simulation models – ex: Many interconnect subroutines, objects in video game
