graph Styles Question [1]: [25 marks] A combinational circuit is divided into two sub-circuits N1 and N2 as shown. The truth table for N1 is given. Assume that the input combinations ABC = 111 and ABC =000 never occur. 1- Complete the truth table. 2- Write Das minterms expansion and Fas Maxterms expansion (Decimal notation). 3- Determine the Boolean expression of Z in terms of D, E and F as Maxterms expansion (Decimal notation) 4 Simplify the expressions of D, E and Fas minimum Products of Sum. 5- Design the circuit of N, as minimum NOR-NOR implementation.
