Introduction
In the course digital logic, we learn about the number system, Boolean algebra, basic gates, and logic circuit. We had know to use Boolean algebra to simplify the Boolean expression to design a simplest circuit to the needed. We had doing lab to use the IC of some basic gates:AND,OR, NOR,NAND and Latches with Flip-Flops in logic circuit. We also know to design circuit that fulfill to satisfactions of the requirement.
