INTRODUCTION

A logic gate is an electronic circuit that performs a logical operation on one or more inputs and produces a single output. Logic gates are the basic building blocks of digital electronics.

There are seven basic types of logic gates: AND, OR, NOT, NAND, NOR, XOR, and XNOR. All other logic gates can be constructed from these seven basic gates.

Each logic gate has a unique symbol that represents the logic gate type. The truth table for a logic gate shows the output of the gate for all possible combinations of inputs.

The AND gate is a basic logic gate that produces an output of 1 (TRUE) only if all of its inputs are 1 (TRUE). If any of the inputs is 0 (FALSE), the output is 0 (FALSE).

The OR gate is a basic logic gate that produces an output of 1 (TRUE) if any of its inputs are 1 (TRUE). If all of the inputs are 0 (FALSE), the output is 0 (FALSE).

The NOT gate is a basic logic gate that produces an output of 1 (TRUE) only if its input is 0 (FALSE). If the input is 1 (TRUE), the output is 0 (FALSE).

The NAND gate is a logic gate that produces an output of 0 (FALSE) only if all of its inputs are 1 (TRUE). If any of the inputs is 0 (FALSE), the output is 1 (TRUE).

The NOR gate is a logic gate that produces an output of 0 (FALSE) if any of its inputs are 1 (TRUE). If all of the inputs are 0 (FALSE), the output is 1 (TRUE).

The XOR gate is a logic gate that produces an output of 1 (TRUE) if the number of 1 (TRUE) inputs is odd. If the number of 1 (TRUE) inputs is even, the output is 0 (FALSE).

The XNOR gate is a logic gate that produces an output of 0 (FALSE) if the number of 1 (TRUE) inputs is odd. If the

WHAT ARE LOGIC GATES?

Logic gates are the basic building blocks of any digital circuit. They are used to implement Boolean functions, which are the basis for all digital circuits.

There are three basic types of logic gates: AND, OR, and NOT. These three gates can be combined to form all the other logic gates.

The AND gate is the simplest of the three basic gates. It has two inputs and one output. If both inputs are 1, then the output is 1. If either input is 0, then the output is 0.

The OR gate is similar to the AND gate, but it has two inputs and one output. If either input is 1, then the output is 1. If both inputs are 0, then the output is 0.

The NOT gate is the inverse of the AND gate. It has one input and one output. If the input is 1, then the output is 0. If the input is 0, then the output is 1.

These three gates can be combined to form all the other logic gates.

The AND, OR, and NOT gates are the basic building blocks of digital circuits. They are used to implement Boolean functions, which are the basis for all digital circuits.

PIN DIAGRAM OF LOGIC GATES

A logic gate is an electronic device that performs a logical operation on one or more inputs and produces a single output. The most common types of logic gates are AND, OR, NOT, NAND, NOR, and XOR.

The basic operation of a logic gate is defined by its truth table, which specifies the output of the gate for all possible combinations of input values. For example, the truth table for a two-input AND gate is shown in Figure 1.

As you can see from the truth table, the output of an AND gate is 1 only when both inputs are 1. If either input is 0, the output is 0.

The truth table for a two-input OR gate is shown in Figure 2.

As you can see, the output of an OR gate is 1 when either or both of the inputs are 1. The only time the output is 0 is when both inputs are 0.

The truth table for a NOT gate is shown in Figure 3.

As you can see, the output of a NOT gate is the inverse of the input. If the input is 1, the output is 0. If the input is 0, the output is 1.

The truth table for a two-input NAND gate is shown in Figure 4.

As you can see, the output of a NAND gate is 0 only when both inputs are 1. If either input is 0, the output is 1.

The truth table for a two-input NOR gate is shown in Figure 5.

As you can see, the output of a NOR gate is 1 only when both inputs are 0. If either input is 1, the output is 0.

The truth table for a two-input XOR gate is shown in Figure 6.

As you can see, the output of an XOR gate is 1 only when the inputs are different. If the inputs are the same, the output is 0.

Now that you know the basic operations of the most common types of logic gates, let’s take a look at how they are typically represented in a circuit.

TYPES OF LOGIC GATES

As we all know, a digital circuit is based on a number of logic gates. Depending on their function and the number of input and output pins, these logic gates are classified into various types. The basic logic gates are AND, OR, NOT, NAND, NOR, and XOR.

In this article, we will discuss the different types of logic gates with their truth tables and symbol representations.

AND Gate:

An AND gate is a digital logic gate that gives an output of 1 only when all its inputs are 1. If any of the inputs is 0, then the output is 0.

The Boolean expression of an AND gate is denoted by Z = A.B, where A and B are the input variables and Z is the output variable.

The truth table of an AND gate is shown below.

From the truth table, it is clear that the output of an AND gate is 1 only when both the inputs are 1. Otherwise, the output is 0.

The symbol and the circuit diagram of an AND gate are shown below.

OR Gate:

An OR gate is a digital logic gate that gives an output of 1 when any of its inputs is 1. If all the inputs are 0, then the output is 0.

The Boolean expression of an OR gate is denoted by Z = A+B, where A and B are the input variables and Z is the output variable.

The truth table of an OR gate is shown below.

From the truth table, it is clear that the output of an OR gate is 1 when any of the inputs is 1. If all the inputs are 0, then the output is 0.

The symbol and the circuit diagram of an OR gate are shown below.

NOT Gate:

A NOT gate is a digital logic gate that gives an output of 1 only when its input is 0. If the input is 1, then the output is 0.

The Boolean expression of a NOT gate is denoted by Z = A’, where A is the input variable and Z is the output variable.

The truth table of a NOT gate is shown below

APPLICATIONS OF LOGIC GATES

Logic gates are electronic components that are used to build digital circuits. There are several types of logic gates, each with a specific function. The most common types of logic gates are AND, OR, and NOT gates.

AND Gates:

AND gates are used to create logic circuits that require two or more inputs to be active in order to produce an output. For example, an AND gate could be used to create a circuit that turns on a light only when two switches are turned on.

OR Gates:

OR gates are used to create logic circuits that require one or more inputs to be active in order to produce an output. For example, an OR gate could be used to create a circuit that turns on a light when either of two switches is turned on.

NOT Gates:

NOT gates are used to create logic circuits that invert the state of an input. For example, a NOT gate could be used to create a circuit that turns on a light when a switch is turned off.

NAND Gates:

NAND gates are used to create logic circuits that require two or more inputs to be active in order to produce an output. NAND gates are similar to AND gates, but they invert the state of their output. For example, a NAND gate could be used to create a circuit that turns on a light only when two switches are turned off.

NOR Gates:

NOR gates are used to create logic circuits that require one or more inputs to be active in order to produce an output. NOR gates are similar to OR gates, but they invert the state of their output. For example, a NOR gate could be used to create a circuit that turns on a light when either of two switches is turned off.

CONCLUSION

As we have seen, the logic gates are the basic building blocks of any digital circuit. These gates are implemented using electronic switches like transistors, diodes, etc. and are given specific names and symbols. Each logic gate performs a specific logical function and is the basic unit of any digital system.

Now that we have seen the pin diagram of the 7 basic logic gates, let’s put them all together to see how a digital circuit is designed.

A digital circuit is made up of a number of logic gates connected together to perform a specific function. The truth table of the function is used to determine the required combination of gates. The output of one gate is connected to the input of another gate and so on, until the final output is obtained.

The pin diagram of each gate is used to determine the connection of the input and output pins. The input and output pins of the gates are connected together using wires. The order in which the gates are connected is very important as it determines the function of the circuit.

The following is an example of a digital circuit that performs the OR function.

As we can see, the output of the OR gate is 1 only when either of the inputs is 1. If both the inputs are 0, then the output is 0.

This digital circuit can be designed using any combination of logic gates. The most common gates used in digital circuits are AND, OR, and NOT gates.
