ECE 220 – Signals and Systems IFall 2008Lecture: Monday and Wednesday 1.30-2.45, King Hall 2053Lab: Monday 10.30-12.20; Tuesday or 10.00-11.50, ST-I, Room 128Recitation: Friday 1.30-2.20 (RA101) or Friday 2.30-3.20 (IN316) Course Instructor: Janos GertlerST-II, Room 259, [email protected], 993-1064Office hours: Monday and Wednesday, 3.30-4.30 Lab Instructor: Nikita Charankar, [email protected] Recitation Instructor/Grader: Mohammad Ghorbanzadeh, [email protected] Prerequisite: C or better in ECE 201Corequisites: MATH 203 and 214 Textbooks: 1. Signals and Systems (Second Edition), by Alan V. Oppenheim and Alan S. Willsky, Prentice-Hall, 1997. (This same book will be used in ECE 320.) 2. Fundamentals of Electric Circuits (Third Edition), by Charles K. Alexander and Matthew N.O. Sadiku, McGaw-Hill, 2004. (This same book is used in ECE 280.) Goals: the course introduces the students to some of the basic concepts and mathematical techniques of signals and systems, that provide the foundations to further studies and practice in various areas of electrical engineering, including circuit analysis, signal processing, communications and control. Theoretical work is supplemented with hands-on laboratory exercises in MATLAB. Subjects: Part I. (book: Oppenheim and Willsky, chapters 1 and 2) Basic signal and system properties Linear time-invariant systems, convolution, impulse response and properties Differential equation description of time-invariant systemsPart II (book: Alexander and Sadiku, chapter 15) Laplace transformation, definition, properties Inverse Laplace transformation Convolution property Laplace transform solution of differential equations Part III (book: Oppenheim and Willsky, chapters 3 and 4) Fourier series expansion of periodic signals Frequency response, Bode plot Basic filtering Fourier transform of continuous-time signals Course work: Lecture, two 75 minute sessions per week Recitation, one 50 minute session per weekLaboratory, one 110 minute session per week Homework, assigned every week, collected one week later6 laboratory assignmentsTwo midterm exams, in-class, 75 minutes, covering Part I and Part IIFinal exam, in-class, consisting of Third exam, covering Part III (75 minutes) Optional retake of Exam I or II (75 minutes) Course grade: Exams 3x20% 60% Lab projects 6x5% 30% (individual work required!)
