Although plus/minus grades will typically not be assigned for the final grade in this course, in some instances, plus/minus grades may be issued. Attendance is not specifically calculated as part of your grade, but regular attendance is required to maintain a firm grasp of the material and to do well in this course. I will consider your regular attendance favorably in determining your final grade if you are on the borderline.
Students with disabilities may request appropriate academic accommodations from the Division of Diversity and Community Engagement, Services for Students with Disabilities, 471-6259.
By UT Austin policy, you must notify me of your pending absence at least fourteen days prior to the date of observance of a religious holy day. If you must miss a class, an examination, a work assignment, or a project in order to observe a religious holy day, you will be given an opportunity to complete the missed work within a reasonable time after the absence, provided you have recieved prior approval from Prof. Rappaport at least 14 days in advance.
There is a typo in the Table B-1, on page 680, for the Poisson Distribution.
The Poisson PDF should have a delta function that is a function of (x – k). Unfortunately, the typo shows the delta function as (xk), which makes no sense.
Please correct this in your book!

Faculty in the ECE Department are committed to detecting and responding to all instances of scholastic dishonesty and will pursue cases of scholastic dishonesty in accordance with university policy. Scholastic dishonesty, in all its forms, is a blight on our entire academic community. All parties in our community — faculty, staff, and students — are responsible for creating an environment that educates outstanding engineers, and this goal entails excellence in technical skills, self-giving citizenry, and ethical integrity. Industry wants engineers who are competent and fully trustworthy, and both qualities must be developed day by day throughout an entire lifetime. Scholastic dishonesty includes, but is not limited to, cheating, plagiarism, collusion, falsifying academic records, or any act designed to give an unfair academic advantage to the student. Penalties for scholastic dishonesty are severe and can include, but are not limited to, a written reprimand, a zero on the assignment/exam, re-taking the exam in question, an F in the course, or expulsion from the University. Please do not jeopardize your career by an act of scholastic dishonesty. Details about academic integrity and what constitutes scholastic dishonesty can be found at the website for the UT Dean of Students Office and the General Information Catalog, Section 11-802.
