Unformatted text preview: The input combination (x,y,z,w) = (0,0,1,1) never occurs. Simplify the circuit such that the simplified and the old circuit produce the same output values for those input combinations that may occur. (5p)5. Construct a 4-to-16 line decoder with five 2-to-4 line decoders with enable. (5p) 6. A combinational circuit is defined by the following three Boolean functions: F1= xyz+xz F2=xyz+yz F3=xyz+xy Design the circuit with a decoder and external gates. (5p) 7. Construct a 16x1 multiplexer with two 8x1 and one 2x1 multiplexers. Use block diagrams. (5p) 8. Implement the following Boolean function using a multiplexer of the smallest possible size. F(A,B,C,D) = (0,2,4,6,8,11,12,15) x y z w a b c F d...
