This is the first course in a two course sequence, the second being ELEC 242 taught in the spring semester.
University Disability Accommodation Policy
Any student with a documented disability needing academic adjustments or accommodations is requested to speak with the course instructor during the first two weeks of class. All discussions will remain confidential. If you have a documented disability that may affect academic performance, you should: 1) make sure this documentation is on file with Disability Resource Center (Allen Center, Room 111 / email@example.com / x5841) to determine the accommodations you need and 2) meet with the instructor to discuss your accommodation needs.
