A combinational circuit is divided into two sub-circuits N1 and N2 as shown. The sub-circuit N1 performs the division of the binary number ABC by two. The outputs ED represent the quotient (result) of the division and F represents the remainder. The sub-circuit N2 has Z as an output. N2 Z B DB 1- Write the expression of Z in terms of D, E, and Fas sum of product. 2- Complete the truth table of the circuit. ABC FED Z 3- Write D, E and Fas minterms expansion. 4- Write Z as Maxterms expansion in terms of A, B, and C
