Learning Objectives (Indicators)  

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

  1. Learn mathematical analysis of non-linear modulated signals (e.g. frequency and phase modulated signals) using Bessel functions and series expansions to estimate their spectra. Learn mathematical formulation and analysis of stochastic signals. (1b)
  2. Study characteristics of communication channels. Learn basic modulation techniques for efficient transmission of signals over communication channels. Learn modulation techniques to counteract frequency-dependent limitations of transmission (attenuation, frequency-selective fading). Learn effects of noise on systems and signals. (1c)
  3. Learn to model complete communication systems including transmitter and receiver structures. Study bandwidth efficient communication techniques. Learn to formulate and analyze effects of noise on model communication systems and signal propagation. (2b)
  4. Learn how to use the measurements of AM and FM signals to extract signal characteristics (e.g., modulation indices), so that signal characteristics can be modified to conform to regulatory conditions. (3b)
  5. Study different amplitude- and frequency modulation systems, study their characteristics, power efficiency and limitations. Learn coherent and non-coherent coherent communication systems. (3a)
  6. Learn to conduct lab experiments with specialized test and measurement equipment to measure modulated signal characteristics in time- and frequency domains. Learn to measure modulation indices of modulated signals. (5b)

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).


ExaminationsMidterm exam: Tuesday, Date TBD, 9:00-11:00am, closed-book, problem solving.
 Final exam, during the exam period, three hours, closed-book, problem solving.
 
Other Evaluation InformationStudents must achieve passing grades in both the lecture and the laboratory components of the course in order to pass the course.
Other Information
 
 Assignments:   There are four assignments, which include problems selected from the course reference text.  These questions and their respective solutions are available from the course home page on D2L.  These assignments will neither be collected nor graded; they are provided only as a study guide. You are strongly recommended to attempt to solve the assignment problems on your own without looking at the solutions first. If you have any questions about an assignment problem or its respective solution, please consult the course instructor or the teaching assistant during their consulting hours.

University Policies & Important Information

Students are reminded that they are required to adhere to all relevant university policies found in their online course shell in D2L and/or on the Senate website

Refer to the Departmental FAQ page for furhter information on common questions.

Important Resources Available at Toronto Metropolitan University

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.
