# Differences between Logic Function and Logic Circuit

• Engineering
• Akirien
In summary, the conversation discusses the differences between logic functions and logic circuits, with examples of different circuits such as comparator, multiplexer, adder, register, and shifter. The conversation also touches on how these circuits are represented and the use of operators such as AND, OR, and NOT. It is clarified that each of these circuits has their own logic function.

## Homework Statement

The task required me to find the logic function / circuit for :

a. comparator
b. multiplexer
d. register
e. shifter

So what are the differences between logic function and logic circuit?
Thank you :)

## The Attempt at a Solution

A logic function is just an expression using operators {AND, OR, NOT}.
A logic circuit is basically the drawing corresponding to the function using the gates
AND and OR and the inverter.

Thank you Max for answering my question.. So you mean, all of them like Shifter and Register have their own logic function?

## 1. What is a logic function?

A logic function is a mathematical representation of a logical operation, such as AND, OR, and NOT, which takes one or more inputs and produces a single output based on the given logical rules.

## 2. What is a logic circuit?

A logic circuit is a physical implementation of a logic function, using electronic components such as transistors and logic gates to perform logical operations and produce an output based on the given input signals.

## 3. How are logic functions and logic circuits related?

Logic functions and logic circuits are closely related, as logic functions dictate the logical rules that the circuit must follow, while the circuit physically carries out those rules to produce an output.

## 4. What are some differences between logic functions and logic circuits?

One main difference is that logic functions are abstract mathematical concepts, while logic circuits are tangible physical devices. Additionally, logic functions can be represented using symbols and equations, while logic circuits are typically represented using diagrams and schematics.

## 5. Can a logic function be implemented using different logic circuits?

Yes, a logic function can be implemented using different logic circuits, as long as the circuits follow the same logical rules. There can be multiple ways to physically represent a logic function, each with its own advantages and disadvantages.
