ECE 2030 A 11:00pm Computer Engineering Spring 2011 5 problems, 7 pages Final Exam 6 May 2011 Problem 1 (3 parts, 21 points) “A chip off the old block” Part A (15 points) Consider the five definitions for the block drawn below. One block input is the logical value A . The other input is the control value C . The output behavior for each of the five definitions is given in the table. Complete the full truth table and state the logical (gate) names for each definition. (hint: the first block one appears to mask A when its control input is low.)
