Lectures
I use PowerPoint slides to teach this class.  I recommend you come to class with a copy of these so you spend more time understanding the material than writing notes off the board. You can download the PDF files below and print them at home or on campus.

The lecture movies (MTS) MUST be viewed with VLC Viewer (since the CODEC used for this camera is extremely rare).

Portable Document Format (PDF) documents can be viewed with Adobe Acrobat Reader.
