If we have two Boolean functions F;(A,B,C,D) = E(0,2,4,6,11,13,14,15) a) Obtain simplified SOP for F. Fi using k-maps Implement F, using: b) NAND-AND two level only BAND-NOR c) 8x1 multiplexer a) 4x1 multiplexer e) TWO 3 x 8 decoders and external gates f) 2 x 4 decoders and external gates. g) implement both functions F and F(A,B,C,D) = (0,1,10,11,12,13,14,13) using suitable ROM
