Grades, Mid-terms, and Exams
The following outline is approximate.
Applications and examples are given throughout the course.
- Signals: Continuous, Discrete
- Systems: Continuous, Discrete, Models, States,
Differential and Difference Equations.
- Linear Time-Invariant Systems (LTI): Representation, Delay,time invariance,
- Frequency Domain: Fourier Series, Complex Fourier series,
Frequency Response, Convolution
- Filters: FIR Filters, IIR Filters, design and implementation
- Fourier Transforms
- Sampling Theorem: Aliasing, Nyquist-Shannon Sampling Theorem
Learning objectives are measured and reported to the CEAB as part of the accreditation process.
- Students should know and understand
- Period, Frequency, and normalized frequency for continuous and discrete signals
- Discrete Linear Time Invariant systems, difference equation, state space equation, impulse response, convolution
- The frequency domain. Periodic signals and series, Frequency response, complex exponentials
Fourier transform from discrete and continuous systems.
- Filtering, design of simple second order discrete filters.
- The properties of transforms and applications
- Sampling Theorem, Aliasing
- Block diagrams, feedback loop
- Stability (BIBO) of LTI systems (discrete and continuous) Laplace transform, Z transform, concepts related to signal processing and control.
- Students should be able to
- Transform LTI systems between their different representations (difference equation, state space, impulse response, frequency response, block diagrams.
- Compute the transform of simple signals by hand (constants, impulses, sinodials, ...
- Show understanding in complex numbers, complex exponentials and their application to signals, systems, and applications suck as filtering, and control
- Model simple systems like compound interest, harmonic oscillator, simple feedback loop, ... as systems and use impulse response and transfer function to analyze them
- Design simple digital filters by placing zeros.
"The Faculty of Engineering is concerned with ensuring an
environment that is free of all adverse discrimination. If there is
a problem that cannot be resolved by discussion among the persons
concerned individuals are reminded that they should contact there
Chair, the Sexual Harassment Office or the Human Rights Consultant,
as soon as possible."
You are expected to exhibit honesty and use ethical behavior in all aspects of the learning
Academic credentials you earn are rooted in principles of honesty and academic integrity.
Academic dishonesty is to knowingly act or fail to act in a way that results or could
result in unearned academic credit or advantage. This behavior can result in serious
consequences, e.g. the grade of zero on an assignment, loss of credit with a notation on the
(notation reads: "Grade of F assigned for academic dishonesty?") and/or
suspension or expulsion from the university.
It is your responsibility to understand what constitutes academic dishonesty. For information
on the various types of academic dishonesty please refer to the Academic Integrity Policy,
The following illustrates only three forms of academic dishonesty:
- Plagiarism, e.g. the submission of work that is not one's own or for which other
credit has been obtained.
- Improper collaboration in group work.
- Copying or using unauthorized aids in tests and examinations.
Calculators (the standard McMaster calculator) are used in this course
and their use will be permitted during tests and final.
