You want to design an arithmetic adder/subtractor logic circuit.

(a) List the steps you will apply in the design approach. 8-bit BCD full adder design the circuit. Explain each step. Realize with AND, OR, NOT gates.

(b) In the circuit you designed the numbers 0, 3, 5, 9 discuss the result by summing up.
