Learning Objectives (Indicators)  

At the end of this course, the successful student will be able to:

  1. Review Complex Numbers, Euler's Equation, and Sinusoidal signals and tie those to signal decomposition. Learn linear signal operations and apply them to a variety of linear systems. Learn Fourier series and transforms and underlying math, and apply them in analyzing continuous time signals. Learn about Laplace transform and the underlying math, and use it to analyze solutions to differential equations. (1c)
  2. Learn important signal and system classifications for further processing. For example if a system is Linear and Time invariant, then the output of the system to all inputs can be predicted using the impulse response and using convolution. (3a)
  3. Learn frequency analysis of continuous-time signals and LTI systems and describe differences between Fourier transform and Fourier series analysis. Perform both Fourier transform and Fourier series in hypothetical design and analysis of signals and LTI systems. Analyze result of evaluation to detect if a continuous-time system is Linear Time-Invariant (LTI). To discern additional criteria. In case the system is LTI, additional characteristic of the system (impulse response of the system) is calculated to facilitate calculation and evaluation of the system's output. (4b)
  4. Select and perform strategies to generate information about continuous-time signals (properties such as power or energy finiteness) and systems (properties such as linearity, stability, causality) that may be used to modify, improve, or elaborate a design state. (4c)
  5. Understanding system property and limitation, fundamental problems in sampling. Learning the role of important signals such as sinc and delta and role of them in system design and analysis. (5a)
  6. Read and appropriately respond to technical and non-technical written instructions. Cites evidence to construct and support an argument. Produce four lab reports using appropriate format, grammar, and citation styles for technical and non-technical audiences. (7a)
  7. Illustrate concepts of continuous-time signals and systems through graphical presentation of their properties. (7c)
  8. Finding relationship between signals, building a signal based on other existing basis, signal modulation and its practical issues that can be well explained with the theory. (12a)

Course Evaluation
Theory
Quizzes (5 X 4%) 20 %
Midterm Examination 25 %
Final Examination 35 %
Laboratory
Laboratory Assignments (4 X 5%) 20 %
TOTAL:100 %

Note: In order for a student to pass a course, a minimum overall course mark of 50% must be obtained. In addition, for courses that have both "Theory and Laboratory" components, the student must pass the Laboratory and Theory portions separately by achieving a minimum of 50% in the combined Laboratory components and 50% in the combined Theory components. Please refer to the "Course Evaluation" section above for details on the Theory and Laboratory components (if applicable).


Examinations- Bi-weekly 30-minute quizzes will be administered via D2L every 2 lecture-weeks.
 
 - Midterm will be a 2-hour closed-book exam on Wednesday October 18th during the lecture session (10am-12pm), covering all material previously covered (lectures 1-6).
 
 - Final exam, during exam period, will be a 3-hour closed-book exam, covering all course material with emphasis on the content covered after the midterm.
 
 
Other Evaluation Information- The theoretical lecture material is provided ahead of each lecture in the form of PDF notes and recorded video modules. Students are required to view and download these lecture notes (viewing the recorded videos is not mandatory).
 
 - Lab marks are based on attendance, participation (showing your work, answering TA questions), successful completion of pre-lab problems, completion of experiment steps, lab reports and successful reply to your TA questions during submission. Students will have the responsibility to achieve a working knowledge of the software packages that will be used in the lab.
 
 - Students will complete their lab work in pairs and submit their individual reports through a D2L lab submission link.
 
 - Any concerns about the labs or quizzes should first be addressed to the TAs prior to contacting the course instructor.
Teaching Methods- This course will be delivered using asynchronous teaching, aka flipped classroom approach, where the theoretical material will be posted online ahead of time and the lecture sessions will be dedicated to going over the theory, practicing hands-on problem solving, and discussing real-life applications.
 
Other Information* Note that not all material covered during the lecture time will be posted online. Students are responsible for the material covered in class and in the labs. As such, students are encouraged to attend the lectures and not solely rely on the pre-recorded lectures.
 
 * Attendance in the lab is mandatory - work done at home independently will not be graded.

Accessibility

Academic Accommodation Support

Academic Accommodation Support (AAS) is the university's disability services office. AAS works directly with incoming and returning students looking for help with their academic accommodations. AAS works with any student who requires academic accommodation regardless of program or course load.

Academic Accommodations (for students with disabilities) and Academic Consideration (for students faced with extenuating circumstances that can include short-term health issues) are governed by two different university policies. Learn more about Academic Accommodations versus Academic Consideration and how to access each.

Wellbeing Support

At Toronto Metropolitan University, we recognize that things can come up throughout the term that may interfere with a student’s ability to succeed in their coursework. These circumstances are outside of one’s control and can have a serious impact on physical and mental well-being. Seeking help can be a challenge, especially in those times of crisis.

If you are experiencing a mental health crisis, please call 911 and go to the nearest hospital emergency room. You can also access these outside resources at anytime:

If non-crisis support is needed, you can access these campus resources:

We encourage all Toronto Metropolitan University community members to access available resources to ensure support is reachable. You can find more resources available through the Toronto Metropolitan University Mental Health and Wellbeing website.
