3 hours en functions F (A,B,C,D) = 2(0,1 .C,D) = (0.1.5,9,10,11,13,14,15) or Fy, F, F and Fz using k-maps Question (1) (28 marks equally distributed); If we have two Boolean functions and F2(A,B,C,D) = (0,1,10,11,12,13,14,1 a) Obtain simplified SOP for F, F. F and Implement Fy using: a) NAND-AND two level only b) 8 x 1 multiplexer c) Two 3 x 8 decoders and external gates Implement both functions Fi and Fuusing suitable: d) ROM e) PLA f) PAL with 4x2x2
