CEG/EE 260 Midterm #2 Spring 2007 NAME: 1. (20) Using a Karnaugh map, find ALL the minimal sum of products (SOPs) of the function: F = Σ W,X,Y,Z (0, 1, 2, 3, 4, 7, 8, 10, 11, 12, 15). You need to place a * in every distinguished 1-cell and identify all the essential prime implicants. 1

2. (20) Find all the minimal product of sums (POS) of the function: F = Σ W,X,Y,Z (0, 4, 10) + d (1, 2, 9, 12, 13, 14, 15) 2
3. (30) Implement the logic function F = Σ W,X,Y (0, 2, 3, 5) with the following components. (Feel free to use your own logic symbol, as long as the labeling is clear. You don’t have to use those standard MSI

(1) a 3-to-8 decoder and a OR gate (which is allowed to have more than two inputs) (2) an 8-to-1 multiplexer (and some basic gates if necessary) (3) a 4-to-1 multiplexer (and some basic gates if necessary) (4) 2-to-1 multiplexers (and some basic gates if necessary) 3 4(20 points) (1)Obtain the truth table for the following circuit. (2)Draw an equivalent circuit for F with fewer NAND gates. 4 X Y Z F 5 (10). F=(A+B)(A’+B’), implement this function F using only NOR gates. 5...
