What is a Logic Gate?

Logic Gates Definition

Logic gates are fundamental building blocks of digital electronic circuits. They are devices that perform basic logical functions based on Boolean algebra. A logic gate is a digital circuit that flows information alerts (like messages).

It’s like a selection-making tool that takes in one or more inputs and produces an output based totally on certain regulations.

Think of a logic gate like a smart friend in your computer. This friend takes in messages (called signals) through one or more doors. If the messages are like saying “yes” (on/high), the friend reacts one way.

If the messages are like saying “no” (off/low), the friend reacts differently. The friend’s reaction depends on what kind of decision rule it follows.

These good judgment gates are like the superheroes of your computer and different electronic stuff. They’re anywhere, ensuring things paint smoothly.

You’ll locate them on your computer, alarms, streetlights, and more, helping these things make smart selections based on the signals they get.

Logic Gates Formula

Look at some of the basic formulas for some common logic gates.

Logic Gate Boolean Expression

AND Gate: Output (Y) = Input1 (A) AND Input2 (B)
Symbolically: Y = A * B

OR Gate: Output (Y) = Input1 (A) OR Input2 (B)
Symbolically: Y = A + B

NOT Gate (Inverter): Output (Y) = NOT Input (A)
Symbolically: Y = NOT A

NAND Gate: Output (Y) = NOT (Input1 (A) AND Input2 (B))
Symbolically: Y = NOT (A * B)

NOR Gate: Output (Y) = NOT (Input1 (A) OR Input2 (B))
Symbolically: Y = NOT (A + B)

XOR Gate (Exclusive OR): Output (Y) = (Input1 (A) AND NOT Input2 (B)) OR (NOT Input1 (A) AND Input2 (B))
Symbolically: Y = (A * NOT B) + (NOT A * B)

XNOR Gate (Exclusive NOR): Output (Y) = NOT ((Input1 (A) AND NOT Input2 (B)) OR (NOT Input1 (A) AND Input2 (B)))
Symbolically: Y = NOT [(A * NOT B) + (NOT A * B)]

These formulas represent the logical operations performed by each gate, where “AND”, “OR”, and “NOT” are basic logical operators. The symbols “*”, “+” and “NOT” represent the logical AND, OR, and NOT operations respectively.

What are the Basic Logic Gates?

Logic gates are fundamental components of digital circuits that perform logical operations on binary inputs, ultimately producing binary outputs.

Several forms of basic logic gates are generally utilized in digital electronics. Let’s take a closer look at every one of the Logic Gates symbols and its type.

Logic Gates Symbol

1. AND Gate

The AND gate is one of the simplest logic gates, and it produces an output of “1” only when all of its inputs are “1.”

If any input is “0,” the output will be “0.” For example, if we have two inputs A and B, the truth table for an AND gate is as follows.


OR Gate

The OR gate, like the AND gate, takes multiple inputs and produces a single output. However, in this case, the output is “1”

If any of the inputs are “1.” Only if all the inputs are “0” will the output be “0.” The truth table for an OR gate is as follows


NOT Gate

The NOT gate, also known as an inverter, takes a single input and produces the opposite value as the output.

If the input is “1,” the output will be “0,” and vice versa. The truth table for a NOT gate is as follows.


Combination of Basic Logic Gates

Now that we’ve covered the basic logic gates, let’s explore how they can be combined to create more complex circuits.

By combining different logic gates, we can perform a wide range of logical operations and create more complex systems. Here are a few examples:

1. NAND Gate

One of the most versatile logic gates is the NAND gate, which stands for “NOT AND.” It can be constructed by combining an AND gate and a NOT gate.

The output of a NAND gate is the opposite of an AND gate. It produces a “0” only when all of its inputs are “1,” and “1” otherwise. The truth table for a NAND gate is as follows.


NOR Gate

Similarly, the NOR gate, which stands for “NOT OR,” is constructed by combining an OR gate and a NOT gate. The output of a NOR gate is the opposite of an OR gate.

It produces a “1” only when all of its inputs are “0,” and “0” otherwise. The truth table for a NOR gate is as follows.


XOR Gate

The XOR gate, short for “exclusive OR,” produces a “1” only when its inputs are different. If the inputs are the same, the output will be “0.”

This gate can be constructed by combining multiple basic gates like AND, OR, and NOT gates. The truth table for an XOR gate is as follows.


Using Logic Gate Calculator to process Boolean Expressions

Logic gate calculators enable users to input boolean expressions and perform logic gate calculations to evaluate the expression.

Logic Gates Truth Table

An AND gate has two inputs (A and B) and one output (Y).

  • Inputs (A and B): Binary signals (0 or 1).
  • Output (Y): Resultant binary signal based on the AND operation.
+—–+ A –| | | AND |—- Y B –| | +—–+

In this diagram,

A and B are the inputs.
The AND gate processes the inputs.
Y is the output.
According to the truth table:

Y is 1 only when both A and B are 1; otherwise, Y is 0.
This AND gate is just one example. More complex circuits can be created by combining multiple gates to perform more intricate logical operations.

Digital circuits use these logic gates in various combinations to implement the functions necessary for digital computing, communication, and control in electronic devices.

What do you mean by logic gate a+b?

The expression “a + b” represents the logical OR operation between inputs ‘a’ and ‘b’. In other words, the output is true if at least one of the inputs ‘a’ or ‘b’ is true. Here’s how it’s represented symbolically:

Y = a OR b

Or, using the Boolean algebra notation:

Y = a + b
