Laboratory: There will be a series of six or seven Matlab assignments to be
completed in the laboratory. The laboratory assignments are a
required component of the course. Failure to complete the lab
assignments will result in a failing grade for the course.
Notes: O/W indicates a reading assignment in the Oppenheim/Willsky textbook. A/S indicates a
reading assignment in the Alexander/Sadiku textbook.
