How to Build a 4:1 Multiplexer and 2:4 Decoder Using Logic Gates in Logisim | Step-by-Step Tutorial

Welcome to the ultimate beginner-friendly guide on digital logic design! In this video, I’ll walk you through how to manually build a 4:1 Multiplexer and a 2:4 Decoder using ONLY AND, OR, and NOT gates in Logisim.

🔧 Whether you're a computer engineering student, a digital logic newbie, or prepping for a project or exam, this tutorial has everything you need to understand how these essential components work at the gate level.

📌 What You’ll Learn:

What a multiplexer and decoder actually do

How to build a 4:1 MUX using logic gates (step-by-step)

How to build a 2:4 decoder using logic gates (step-by-step)

The key difference between a MUX and a decoder

Practical uses for both in real-world circuits

🧠 Quick Concepts:

Multiplexer = select one input, send it to output

Decoder = activate one output based on input combo

💻 Tools Used:

Logisim (Free logic circuit simulator)
