Theory: In a Logic circuit, basic elements called gates collectively make up the circuit. A gate is simply an input/ output device. When the device accepts inputs, one or more outputs based on the choice of one’s combination are returned. Usually, two logic levels such as “0” and “1” are used. An equation expresses the relationship between the input and output called the logic equation or logic function. This equation determines the value of output if the input values are known. A unique mathematics called “Boolean Algebra” solely allows one to handle the logic functions due to the fact that any variable in digital electronics can accept one of the two values 0 or 1. Logic gates which use only “0” and “1” in both the input and output can suitably be represented in a table governing all combinations of a particular gate. This table is referred to as the “Truth Table”. There are three various ways logic gates can be represented: The logical circuit, the truth table, and the Boolean expression. In this experiment, gates; NOT, AND, OR, NAND NOR, XOR, and XNOR are all studied and used. Each entry presents the name, the symbol (circuit), the truth table, and the Boolean Expression for the gate. The XOR and XNOR gates are specifically important and commonly used logic
