## XNOR Gate | Symbol, Truth table & Circuit

A XNOR gate is a gate that gives a true (1 or HIGH) output when all of its inputs are true or when all of its inputs are false (0 or LOW). An XNOR gate is also called exclusive NOR gate or EXNOR gate. In a two input XNOR gate, the output is high (logic 1 … Read moreXNOR Gate | Symbol, Truth table & Circuit

## XOR Gate | Symbol, Truth table & Circuit

A XOR gate is a gate that gives a true (1 or HIGH) output when the number of true inputs is odd. An XOR gate is also called exclusive OR gate or EXOR. In a two input XOR gate, the output is high or true when two inputs are different. In Boolean expression, the term XOR … Read moreXOR Gate | Symbol, Truth table & Circuit

## NOR Gate | Symbol, Truth table & Circuit

A NOR gate is a combination of an OR gate and NOT gate. If we connect the output of OR gate to the input of a NOT gate, the gate so obtained is known as NOR gate. This gate is also called as Negated OR gate. In Boolean expression, the NOR gate is expressed as and is being … Read moreNOR Gate | Symbol, Truth table & Circuit

## NAND Gate | Symbol, Truth table & Circuit

A NAND gate is a combination of an AND gate and NOT gate. If we connect the output of AND gate to the input of a NOT gate, the gate so obtained is known as NAND gate. This gate is also called as Negated AND gate. In Boolean expression, the NAND gate is expressed asand is being … Read moreNAND Gate | Symbol, Truth table & Circuit

## OR Gate | Symbol, Truth table & Realization

OR gate is a device which has two or more inputs and one output. The output of an OR gate is logical 1 (high) only if one or more inputs are logical 1 (high). In Boolean algebra, the term OR is represented by plus (+) and the Boolean expression Y = A+B indicates Y equals … Read moreOR Gate | Symbol, Truth table & Realization

## AND Gate | Symbol, Truth table & Realization

AND gate is a device which has two or more inputs and one output. The output of an AND gate is logical 1 only if all the inputs are logical 1. In Boolean algebra, the term AND is represented by dot (.) and the Boolean expression Y = A.B indicates Y equals A AND B. … Read moreAND Gate | Symbol, Truth table & Realization

## NOT Gate | Symbol, Truth table & Realization

The NOT gate is a device which has only one input and one output. It is a logical gate which inverts the input digital signal. That is why NOT gate is also known as Inverter. In Boolean algebra, the term NOT is represented by bar symbol (‾) and the Boolean expression indicates that Y equals not … Read moreNOT Gate | Symbol, Truth table & Realization

## Decoders | Types & Applications

Decoder is a combinational circuit that has ‘n‘ input lines and maximum of 2n output lines. One of these outputs will be active High based on the combination of inputs present, when the decoder is enabled. It means that Decoder detect a particular code. The output of the decoder are nothing but the min terms … Read moreDecoders | Types & Applications

## Hexadecimal Number System | Conversions

In this article, we will learn another numbering system, known as hexadecimal number system. It has a base of sixteen (16). It means that there are sixteen digits with the help of which we can represent any number of the hexadecimal family. The digits are (0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, … Read moreHexadecimal Number System | Conversions

## Octal Number System | Conversions

In this article, we will learn another numbering system, known as octal number system. It has a base of eight (8). It means that there are eight digits with the help of which we can represent any number of the octal family. The digits are from 0 to 7 i.e. (0, 1, 2, 3, 4, 5, 6, 7). Representation … Read moreOctal Number System | Conversions
