1. The Boolean function F = A' ? A ? A ? 0 is:
a) Equal to 0 b) Equal to 1 c) Equal to A' d) Equal to A e) None of the above.
2. An 8-to-1 multiplexer has inputs A, B, and C connected to the selection inputs. The data inputs are:
L0 = L1 = L2 = L3 = L4 = L5 = L6 = 1, and L7 = D'. The function F(A,B,C,D) that the multiplexer
implements is:
a) (ABCD)' b) ABCD c) (A + B + C + D)' d) A ? B ? C ? D e) (A ? B ? C ? D)'
3. The simplified POS expression for the Vote-taker Boolean function F(A,B,C) = ? (3, 5, 6, 7) is
a) (A' + B)(B + C)(A + C) b) (A + B)(B + C)(A + C)
c) (A + B)(B' + C)(A + C) d) (A + B)(B + C)(A' + C)
