ECE 300 Signals and Systems Fall 2008 Dr Bob Throne x 8414 Room D 221 Text Fundamentals of Signals and Systems by M J Roberts McGraw Hill 2008 GRADING POLICY 3 Exams Final Exam Labs Homework Matlab Prelab work Quizes Lab Practical 10 each 30 10 10 5 5 10 Notes 1 In general you must have a passing average greater than or equal to 60 on the exams to pass the class The quizzes will count as part of this exam average 2 While each exam except the final will focus on material since the previous exam you are responsible for all previous material Anything covered from the beginning of class up until the time of an exam is fair game for the exam 3 Homework assignments are due at the beginning of class on Tuesday No late homework will be accepted without prior approval 4 You must acceptably complete each lab to pass the class 5 Prelabs will be part of your homework assignment Each person is to do the prelab problems 6 You are expected to do your own work You can certainly talk with each other and help each other but the work you hand in should be your own As an example if two people hand in the same Matlab and both came from the same directory neither will receive any points 7 Unless specifically told otherwise on a particular problem you are expected to work out the problem by hand or use Matlab Quizes Each week we will have a quiz usually though not always on Thursday Usually before the quiz I will post a practice quiz to give you an idea of the kinds of problems I expect you to be able to solve on that week s quiz Labs A portion of your course grade is derived from your work in the laboratory exercises chosen to enhance the lecture material and your learning You must want to participate to learn this material and you will be rewarded for your work PASS NOTHING UP that is the only way to truly learn DO NOT let your lab partner do the work for you Your primary means of recording your work for the laboratory is by means of a worksheet or memo Most labs will be done individually while a few will be done with a lab partner 1 Each lab is worth 10 points 2 Labs are due at the end of your lab period 3 Your grade in the laboratory is determined by your lab work 4 You will be required to turn in your Matlab code at the end of most of the labs The code should be written specifically for the problem you are solving or you will lose points A good idea is to copy the code you need to a new file then remove the pieces you do not need once the code is working 5 You will only be allowed to bring your lab assignments and laptop to the lab practical it is to your advantage to keep well maintained lab worksheets and make sure any software used or developed in lab is on your laptop Course Objectives After completing this course the student shall be able to 1 2 3 4 5 6 7 Represent a variety of signals and system responses both mathematically and graphically Appropriately characterize signals Appropriately characterize systems Determine the average power DC value and RMS value of a signal Perform convolution both analytically and graphically Determine and relate the impulse and step response of a system Represent a periodic signal by a Fourier series and describe its frequency content from that representation 8 Predict the output of a filter excited by an arbitrary periodic or aperiodic input waveform 9 Represent a signal or an impulse response by a Fourier transform 10 Use standard Fourier transform pairs and properties to simplify calculation of forward and inverse transforms of both energy and power signals 11 Classify filters as lowpass highpass bandpass or bandstop Interpret lowpass and bandpass filter specifications and understand the concept of distortion 12 Find and sketch the time and frequency domain representations of a signal
