INTRODUCTION A gate is a digital circuit that follows certain logical relationship between the input and output voltages. Therefore, they are generally known as logic gates — gates because they control the flow of information. The five common logic gates used are NOT, AND, OR, NAND, NOR. Each logic gate is indicated by a symbol and its function is defined by a truth table that shows all the possible input logic level combinations with their respective output logic levels. Truth tables help understand the behavior of logic gates. These logic gates can be realized using semiconductor devices. Here we will investigate on the working of first three logic gates i.e. OR, AND, and NOT gate.
OBJECTIVE OF THE PROJECT
To demonstrate the working of logic gates using torch bulb, battery and switches.
APPARATUS REQUIRED
To demonstrate the working of the logic gates we require the following apparatus:-
i) A BATTERY OF 6 V. ii) TWO SWITCHES (KEYS). iii) TORCH BULB. iv) CONNECTING WIRES
THEORY
There are three basic logic gates: 1. The OR Gate * An OR gate has two or more inputs with one output. It operates in such a way that a output is high (i.e. 1) if one of the two inputs (or both the inputs) is high. The symbol of OR Gate is It works on the following truth table:-
2. The AND GATE * An AND gate has two or more inputs and one output. It operates in such a way that the output is high (i.e.
