an functions Fi(A,B,C,D) = 20 11,12,13,14,15). Op for F1, F1, F2and F2 using k-maps ,0) = (0.1.5.9.10,11,13,14,15) 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 a) Obtain simplified SOP for F1, F Implement Fi 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 Fzusing suitabl d) ROM
