## ELE 201: Information SignalsProf. Paul Cuff, Princeton University, Spring Semester 2013-14.
## Course DescriptionSignals that carry information play a central role in technology and engineering — signals ranging from sound and images to sensors, radar, communication, MRI, ultrasound, touch-screens, GPS, and robotic control. This course teaches mathematical tools to analyze, manipulate, dissect, and preserve information signals. We discuss how continuous signals can be perfectly represented through sampling (Nyquist theorem), which leads to the use of digital signals. A major focus of the course is the Fourier transform — how, when, and why to use it. We also study linear time-invariant systems, modulation, quantization, and stability (using the related Laplace transform and z-transform). The learning is applied in design projects using Matlab, such as a “Shazam” music identification system. Topics: transforms for signal analysis (Fourier in particular) linear time-invariant systems filtering and signal processing sampling and modulation compression and error-correction stability
Labs: Shazam music-identification system MP3 audio compression

Please use Piazza for communication with the teaching staff. See the explanation below on this page. ## Time and Location## LecturesRoom: Friend 004 ## Lab SessionsMonday: 1:30-4:20pm ## Office HoursTuesday: 4:30-5:30pm (Sai Satpathy in F-110 E-Quad) ## TextThe following textbook is required: Signals and Systems, second edition. Oppenheim and Willsky with Nawab. Also, course notes provided by Prof. Kulkarni are available online. ## MatlabMatlab will be used in each of the labs for this course. We don't assume that you have used Matlab before. The first few labs will be introductory. ## PiazzaPlease use Piazza (www.piazza.com) for all electronic communications with the teaching staff rather than email. This approach should help you obtain answers speedily. Piazza is a question-and-answer platform specifically designed to get you answers fast. They support LaTeX, code formatting, embedding of images, and attaching of files. We encourage you to ask questions when you're struggling to understand a concept – you can even do so anonymously.
## BlackboardBlackboard will only be used for communicating grades on assignments and exams and for distributing solutions (not intended for the eyes of future students). The lab door code can also be found in the Blackboard announcements. |
