Catalog Level Description:
Primer on digital audio. Overview of signal
processing, sampling, compression, human psychoacoustics, MP3, intellectual
property, hardware and software platform components, and networking
(i.e., the basic technical underpinnings of modern MP3 players and cell phones).
Content
Projected topics by week:
- Overview
- Sampling / PCM / Digital Audio
- Lossless compression
- Time-Frequency Conversion
- Nyquist-Shannon sampling theorem
- Human Perception
- Psychoacoustical Compression
- Hardware Organization
- Operating System (sharing hardware)
- File System
- Networking
- User Interface
- Intellectual Property
Course Objectives
By the end of theh course, you will be able to:
- perform mathematical optimization for audio encoding
- conduct and analyze psychoacoustic experiments (frequency
sensitivity and masking, sampling and aliasing)
- conduct and analyze networking experiments
- identify and quantify tradeoffs between quality and costs
- conduct and analyze experiments to understand hardware bottlenecks
and software behavior
- design a file system for multiple access views
- demonstrate understanding of the role of Intellectual Property
- appreciate role of User Interfaces and making technology usable by lay public
- identify applications enabled or impacted by compression
- understand how hardware performance enables new capabilities
- understand performance of contemporary hardware elements
- use an oscilloscope to analyze an audio waveform
- program for simple signal processing and visualization tasks (e.g., matlab)
- program lossless compression
- use spreadsheets to generate data for experiments
- use performance counters for benchmarking and profiling application performance
- write a formal lab report
Grading
Grading is based on:
- Quizzes and Class Participation [10%]
- Weekly Lab Writeups [50%] (will drop lowest attempted lab; not turning in a
lab writeup does not count as an attempt)
- One Formal Lab Report [20%]
- Midterm [5%]
- Final [15%]
| Grade | Percent Point Range |
|---|
| A | 100--85 |
| B | 84--75 |
| C | 74--65 |
| D | 64--50 |
| F | 49--0 |
(If you score in the specified range, you will at least receive the
stated grade. We reserve the right to be more generous.)
Policies
Writeups
Writeups must be done in electronic form and submitted through
Canvas (below).
Each individual should turn in a lab writeup.
Labs will be performed in pairs and joint data collection and in-lab work
is expected. Pre-classPrelab and final writeups should be done individually.
Formal lab report writeup should be done individually.
Homework Turnin
All assignments will be turned in electronically through the Penn Canvas
website. Log in to canvas with your PennKey and password, then select ESE 150 from the Courses and Groups dropdown menu.
Select Assignments from the links on the left and select the assignment you
wish to submit for. Submission should be as a single file (preferably
.pdf).
Late Assignments
Lab reports must be turned in by the published due date to receive credit.
Late assignments will not be accepted.
Academic Integrity
In general, you are expected to abide by Penn's
Code of Academic Integrity. If there is any uncertainty, please ask.
Absentees
Use the Penn Course Absence Report (CAR) in Penn-in-Touch to report
absences.
Credit Adjustment
Make sure you call any problems with grading to our attention immediately
and not later than the next class meeting after they are returned or posted
on canvas. To submit a request for a review of a credit assignment on
a lab assignment send an email to the instructor stating the nature of the
problem and the remedy you desire. We will not consider any requests for
grade adjustments that are submitted later than the one week grace period
after the grades are posted on canvas. You are responsible for checking
your posted grades in a timely manner.
