Unformatted text preview: 1 1. (True/False) Circle T or F on answer sheet. 2 pts each. a) T F ((x + y) . z) = (x . y) + z b) T F x . (X + y) = y + x . y c) T F x + x.y.z = x + x d) T F Given F(x,y) = x . y + x . y then F(x,y) = x.y+ x.y e) T F (A + B) . A = A 2. (Fill in the blank) Be sure to transfer your answers to the answer sheet. 3 pts each. a) (129) 10 = (010000001) 2 b) (-129) 10 = (101111111) 2 in twos complement. c) The Boolean expression F (w,x,y,z) = (x + y).(w+xz + y) expressed in summa- tion of minterm form is F (w,x,y,z) = w,x,y,z (2,3,4,5,6,7,10,12,13) d) The decimal representation of the binary number (010111001) 2 is 185. e) The next state equation for a JK flip-flop is Q * = JQ + KQ . 3. (Multiple choice) Be sure to transfer your answers to the answer sheet. 3 pts each. M1. The dual function of F(A,B,C) = B + AC can be written as a) B.(A + C) b) B + AC c) B(A+C) M2. The output of the circuit shown can be written as: a) A + B + C + D + E + F b) A.B.C + D.E.F c) A.B.C.D.E.F M3. Given the K-Map of a 3-variable function F(A,B,C), the two essential prime implicants are: a) AB and AC b) AC and BC c) BC and BC d) AB and BC e) None of the above A B C D E F AB C 0 1 1 0 1 0 1 1 2 M4. The output of the circuit shown below can be written as:...
