Show how to build each of the following logic functions using one or more 74x138 binary decoders and NAND gates. (Hint: Each realization should be equivalent to a sum of minterms.) (a) F=Σx,y,z (2,5,7) (b) FПIA,B,C(2,4,5,6,7)

2) Show that the output carry in a full-adder circuit can be expressed in theAND–OR–INVERT form correctly

1. A. Convert A5Q(27)→ X(9) 2. Simplify the Karnaugh maps and draw the logic circuit. AB 00 01 11 10 CD 00 1 1 1 1 01 1 1 11 1 1 10 1 1 11 1 AB 00 01 11 10 CD 00 1 1 01 11 1 1 10 11 11 1 1

configuration. Given the following function, F (a, b, c, d) =Σm (0,1,2,5,6,7), find the alternate NAND gate
