QUESTION 1 A combinational circuit is divided into two sub-circuits 1 and N2 as shown The sub-circuit Ni performs the division of the binary number ABC by two. The outputs E and represent the quotient (result) of the division and represents the remainder. The sub-circuit N2 has Z as an output DB 1. Write the expression of Z in terms of D, E, and Fas sum of product. (marks) 2. Complete the truth table of the circuit (5 marks) ABC FED Z 3. Write D, E and F as interms expansion (5 marks) Write Z as Maxterms expansion in terms of A, B, and
