Part 4 1. Consider the K-Maps given below. For each K- Map i. Write the appropriate standard form (SOP/POS) of Boolean expression. ii. Design the circuit using AND, NOT and OR gates. iii. Design the circuit only by using • NAND gates if the standard form obtained in part (i) is SOP. • NOR gates if the standard form obtained in pat (i) is POS.
