McMaster University
CAS-748
Analysis and Synthesis of Sound
Term II 2020/21
Lectures
We, Fr: 9:00AM - 10:30AM
All lectures are life, online in in MS-Teams , you should have access to the CAS 748 team.
Instructor
M. v. Mohrenschildt,
Course Objectives
Make the student familiar with the mathematical, physics, engineering principles,
and the real time related concepts, of signal processing and synthesis related to sound.
We cover the mathematics, implementation aspects, and applications.
Topics include (Fourier, Wavelets, basic music theory, band-limited synthesis, compression)
Course Information on Web

Course Material
No book required. The material is
here.
Assignments and Exams
There will be 3 assignments consisting of experiments, and one final ``presentation/project".
The project is 40% of the final grade the other 3 assignments contribute each 20% to the final
grade.
- There is a zero tolerance on academic dishonesty .
All assignments have to be solved alone, any
outside source, this includes asking other people,
or using any books or information found on the web has to
be documented.
- The final project consists of two parts, a written document and
an oral presentation. It will be judged in equal parts by
correctness, originality of the solution, effort, background research,
and presentation.
- There is a 25% penalty for each day an assignment is handed in late.
This means, an assignment which is more then four days late is
counted as 0.
- Any misunderstanding or problems should be resolved immediately by
contacting the instructor.

Notes:
Discrimination
"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."
Academic Dishonesty
You are expected to exhibit honesty and use ethical behavior in all aspects of the learning
process.
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
transcript
(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,
located at
http://www.mcmaster.ca/academicintegrity .
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
Calculators (the standard McMaster calculator) are used in this course
and their use will be permitted during tests and final.
