1 Name:______________________________________________ Perm #:_____________________________________________ Lab Section TA:______________________________________ ECE 152A-Winter 2008 Prof. Volkan Rodoplu MIDTERM EXAMINATION INSTRUCTIONS: 1. READ THIS PAGE THOROUGHLY WHEN YOU RECEIVE IT, BUT DO NOT START TURNING TO THE OTHER PAGES UNTIL YOU ARE INSTRUCTED TO DO SO. 2. WHENEVER INDICATED, YOU MUST WRITE YOUR ANSWERS ON THE ANSWER LINES PROVIDED IN CERTAIN PROBLEMS. NO PARTIAL CREDIT WILL BE GIVEN ON THESE PROBLEMS. (We will check only the answer on that line.) 3. On other problems, PARTIAL CREDIT will be given only to true statements that make progress towards the correct answer. Partial credit may be given to correct reasoning in developing structures such as K-maps and truth tables in which the variables are clearly labeled. NO partial credit will be given for incorrect statements or statements to which no truth value can be assigned (such as a bunch of numbers or algebraic expressions). NO partial credit will be given for statements that use symbols that the problem statement or you have not defined. NO credit will be given for any work that is not clearly labeled with the part and problem number to which this work provides an answer. 4. All the exam rules in the course syllabus apply to this exam. 5. You may remove the staple from the exam pages, if is more convenient. We will provide a stapler at the end of the exam.
