Description:
ELEC 242 Continuous-Time Signals and Systems (3.0 credits) Continuous-time signals. Properties of continuous-time systems. Linear Time Invariant (LTI) systems. Impulse response and convolution. Systems based on linear constant-coefficient differential equations. Fourier series representation of periodic signals. The Fourier transform representation of signals and Systems. Inverse Fourier transform. Laplace Transform. Inverse Laplace Transform. Unilateral Laplace Transform. Natural and forced responses of linear differential equations. Transfer function and block diagram representation of LTI systems. Time and frequency domain characteristics of ideal and non-ideal filters. Amplitude modulation and demodulation. Lectures: three hours per week. Tutorials: two hours per week. Prerequisite: ELEC 273; ENGR 213.
Graduate Attributes:
This course emphasizes and develops two CEAB (Canadian Engineering Accreditation Board) graduate attributes, at the intermediate level, a) “A knowledge base for engineering”, that is, “Demonstrated competence in university level mathematics, natural sciences, engineering fundamentals, and specialized engineering knowledge appropriate to the program.” and b) “Problem Analysis”, that is, “An ability to use appropriate knowledge and skills to identify, analyze, and solve complex engineering problems in order to reach substantiated conclusions.” These two attributes will be evaluated (each 20%) in the final exam.
Course Learning Outcomes:
Upon successful completion of the course, students will be able to
- Define the main theories such as LTI CT systems, Convolution, impulse response, frequency response, and system function.
- Describe CT signals and systems concepts including LTI systems, Convolution, frequency spectra, Fourier series, Fourier transform, and Laplace transform.
- Apply the above concepts to process signals (through solving theoretical problems and analysis of input/output).
- Demonstrate skills of analyzing and interpreting data and signals such as input and output relation or input and frequency response relation.
Textbook:
Michael D. Adams, Continuous-Time Signals and Systems , University of Victoria Press, Victoria, BC, Canada, Sept. 2013, 308 pages, ISBN 978-1-55058-495-0 (paperback), ISBN 978-1-55058-506-3 (online PDF, http://www.ece.uvic.ca/~frodo/sigsysbook/ ).
Other Course Material:
Assignments, suggested problems, and other required course material will be either given in class or posted on the course website.
Tutorials:
In the tutorials, suggested problems will be solved and your questions will be answered.
Exams:
Two midterms and one final exam will be given. All exams will be closed book. A formula sheet for the second midterm exam and the final may be provided by the instructor. Midterm exams will be held in the lecture time slots on Thursday February 4th and Tuesday March 15th. After each midterm exam, detailed solution will be provided. If you do not write a midterm exam without any legitimate reason, the grade of your midterm exam will be zero. If a student has a legitimate reason not attending a midterm exam, the final exam will include the mark of the corresponding midterm exam. The total midterm exams grade is 40 marks and is calculated based on the better grade of following two schemes:
Scheme 1: Midterm I (30 marks) and Midterm II (10 marks)
Scheme 2: Midterm I (10marks) and midterm II (30 marks)
Assignments:
We suggest a set of 6 assignments which provide hands on experience with the theoretical concepts. They also are the best indicator of what you should expect on exams. There is no substitute for you sitting down and trying these on your own. Assignments are to hand in to the instructor at lectures or to place in the mailbox of the instructor by the due date. Solutions to the assignments will be provided after the due time.

Academic Code of Conduct:
All Concordia University students must abide by the University's code of conduct which can be found in section 17.10 of Concordia University Undergraduate Calendar.
Expectations of Originality:
You have to submit a signed copy of the “Expectations of Originality” form (provided to you with this course outline) to the mailbox of the instructor before submitting the first assignment. In addition, you must write the following statement on the title page of each assignment, then sign and date: “ I certify that this submission is my original work and meets the Faculty's Expectations of Originality ”.
