Introduction to Logic Design/ Digital Logic Design I - Final Examination Question 1 (10 points) A. Converting (153) 10 to base 8 yields which of the following results? (a) 107 (b) 132 (c) 701 (d) 231 (e) 153 B. Converting (0111011.100) 2 to base 16 yields which of the following results? (a) 73.8 (b) 3C.4 (c) 3B.8 (d) 73.4 (e) 3B.4 C. 10100 is the two's complement representation of: (a) -11 (b) +12 (c) -12 (d) -20 (e) +20 D. Simplification of the Boolean expression AB + ABC + ABCD + ABCDE + ABCDEF yields which of the following results? (a) ABCDEF (b) AB (c) AB + CD + EF (d) A + B + C + D + E + F (e) A + B(C+D(E+F)) E. Given that F = (A + B'+ C)(D + E), which of the following represents the only correct expression for F'? (a) F' = A'BC'+ D'+ E' (b) F' = AB'C + DE (c) F' = (A'+ B + C')(D'+ E') (d) F' = A'BC' + D'E' (e) F' = (A + B'+ C)(D'+ E') M. K. Uyguro ğ lu, H. Demirel June 08, 2010
