🔍 Encoder: Working, Functionality & RTL Design 🔍
In this video, we will explore the working and functionality of 4:2 Encoder with detailed explanations.
The video focuses on:

✅ What is an Encoder?
✅ Working and functionality of a 4:2 Encoder
✅ Truth Table and Logic Explanation
✅ RTL Design (Register Transfer Level) using System Verilog

🔍 What is a 4:2 Encoder?
A 4:2 Encoder takes 4 input lines and encodes the active input into a 2-bit binary output. Only one input should be HIGH (1) at a time for proper encoding. It’s used to reduce multiple inputs into fewer outputs for easier processing in digital systems.

he encoder detects which input is high, and generates a binary code representing the position of that high input.

If multiple inputs are high at the same time, it may produce incorrect or undefined results (unless priority is added — for this video, we focus on basic encoding).
