EE 2000 Logic Circuit Design, Semester A, 2007/08 Tutorial 8 The questions are divided into two levels. Level 1 is the basic level question. You should be able to answer them after completing the lecture. Level 2 is the advanced level question. You may have to take a research before answering them. Please be prepared before the tutorial. Level 1 Question 1: Tabulate the PLA programming table and draw the PLA diagram for the following functions. Minimize the number of product terms. A ( x,y,z ) = Σ m (1,2,4,6) B ( x,y,z ) = Σ m (0,1,6,7) C ( x,y,z ) = Σ m (2,6) D ( x,y,z ) = Σ m (1,2,3,5,7)
