Your grade will be assigned on the usual 60, 70, 80, 90 basis. An average above 70 is required to receive a credit (CR/NR).
Attendance: Students are expected to attend lectures. The book covers more information than the class and we will use lectures to map our way through the book. If you miss class you may find it difficult to catch up.
Lab Partners: All labs should be performed with a partner. The lab partnership must be registered with your TA (a simple hand written note signed by both students will suffice) at least a week before the assignment is due. Once registered, the partnership will continue. A partnership can be dissolved only after discussion with the TA. Both partners must be present during the demonstration. It is expected that both partners will contribute to all aspects of each lab, and both partners are expected to be present during the check out. The point values are the same for all labs. The TA will sign your software listing when you demonstrate your system. All parts of the assignment must be demonstrated to a TA by the end of your lab period the week shown in the column labeled "Demo/Report". Any EE345M TA is authorized to checkout your lab.  The report (hardware, software, data and plots) are due one day after the demonstration is due. Please consult with your TA for specific due dates for your lab section.

    You have the option of proposing alternative labs, forming groups of ranging from 2 to 4 students depending on the difficulty of the alternative lab. These groups may include students from other lab sections. The alternative lab must generally cover the same educational objectives as the lab you wish to replace.
    No lab activities occur during the week of August 27-29. During the week of September 2-5, please go to your regularly scheduled EE345M lab in ENS252C to hear a TA explain the lab grading policy. Technological Arts Adapt812 boards will be passed out and lab partners will be selected in your lab the week of September 8-12. The Lab 13 preparation is due at the beginning of your lab the week of September 8-12. Preparation includes hardware wiring diagrams and syntax-free assembly printouts. In other words, please type your software into the PC before lab. The lab preparations (hardware diagrams and syntax-free software source code printouts) are due at the beginning of your lab period. Attendance in lab is required. All software for lab, and tests must include comments. All hardware must include R&C values specifying tolerance and type (e.g., 5% carbon), and TTL chip numbers (be very specific e.g., 74LS00). Pin numbers are required only for lab.

    Students are encouraged to go to the last 2 hours of the other lab periods (including when EE345L labs are scheduled), but the first priority will be to the regular students. Because of the lab quiz, the first hour of lab is restricted to the regular students. CLEAR OUT BY 15 minutes before the start of lab.

Legal Stuff: The 12th class day is September 12. After this date, I will sign a drop only if the Dean approves it. Your current grade status must be a "C" or better for you to receive a "Q". Course evaluation is conducted on the last class day in accordance with the Measurement and Evaluation Center form. The final exam is at the time and place stated in the course schedule. The University of Texas at Austin provides upon request appropriate academic adjustments for qualified students with disabilities. For more information, contact the Office of the Dean of Students with Disabilities at 471-6259, 471-4241 TDD.
Cheating: Cheating is very uncivilized behavior and is to be avoided at all cost. You are allowed to talk to your classmates about the lab assignments, but you are NOT allowed to look at each other's written work. Oral discussion about an assignment is encouraged and is not considered to be cheating. Copying of any part of a program is cheating without explicit reference to its source. If we find two programs that are copied, there will be a substantial penalty to both students, e.g., failure in the course. Students who cheat on tests or in lab will fail. Prosecution of cases is very traumatic to both the student and instructor. PLEASE DO YOUR OWN WORK. Policies concerning the use of other people's software in this class:
    … I strongly encourage you to study existing software.
    … All applications and libraries must be legally obtained. E.g.,
        You may use libraries that came when you bought a compiler.
        You may use software obtained from a BBS or on the WWW.
        You may copy and paste from the existing source code.
    … You may use any existing source code that is clearly referenced and categorized:
        original
: completely written by you,
        derived
: fundamental approach is copied but it is your implementation,
        modified
: source code significantly edited to serve your purpose,
        copied
: source code includes minor modifications.
