Background: Students should have engineering standing and have
completed
A
student who has successfully completed this course should be able to:
1.
Characterize
digital audio systems with difference equations and transfer functions.
2.
Characterize
digital audio signals with correlation functions and power spectra.
3.
Design
systems for processing audio data for applications such as filtering, audio
effects, and signal classification.
4.
Know
the fundamental principles of acoustic energy generation and propagation.
5.
Program
with mathematics software to implement and evaluate designs.
6.
Work
as a team to solve multi-component problems.

Grading scale: For undergraduates 100-90% = A, 90-80% = B,
80-70% =C, 70-60% = D, and 60-0% E.
For
graduates 100-90% = A, 90-80% = B, 80-70% =C, 70-0% E.
Final
Quizzes: Quizzes will be given throughout the semester
to test recently acquired skills / knowledge.
In-class quizzes will typically involve problems that can be solved
without the help of specialized computer software. Take-home quizzes will require the use of
specialized software and the solutions are to be completed independently. There will likely be 6 quizzes, and the 5
highest quiz scores will be taken to compute the final grade. No makeup quizzes will be given. The quizzes primarily assess course outcomes
1 through 4.
Studio Assignments: Studio assignments involve designing,
implementing, and demonstrating a solution to a posed problem with students
working in teams (typically 2 to 3).
Time will be given in class (location will be in a lab with
workstations) to work on the problem with instructor present for interactions. The assignment may extend over several class
periods. Some assignments may require a
short description of the results (a few paragraphs and figures), but all will
require a short demonstration to the class and oral questions from the
instructor directed to individual group members. The final grade will have a common component
based on the solution and how effectively the group worked together, and an
individual component based on responses to questions/contributions and code
written. Commented code should be handed
in where it is clearly identified which team member wrote which components or
version of the code. The studio assignments primarily assess all course
outcomes.
Homework: Homework primarily involves
responding to problems posed in the textbook or in the lecture. Homework assignments focus on the assessment of
outcomes 1 through 4. Late homework
assignments will not be accepted.
Paper Review: For graduate students only, read a research paper (approved first
by instructor) on audio signals/systems and write a critical report on it. The report must accurately summarize what the
authors claim to show, describe their methods, site other related works that
support/contradict the findings, and critically assess the degree to which they
established their claims. The paper review
primarily assesses outcomes 1 through 4.
Unethical behavior (cheating): The following activities are unethical:
·
Using data you
did not measure
·
Recording values
you did not observe
·
Copying a portion
of work belonging to someone else
Any of these will result in
the consequences described in the university’s policy on academic dishonesty.
