In this video, we will learn everything about Priority Encoder in Digital Electronics in a very simple and easy way. A priority encoder is one of the most important combinational circuits used in digital systems. Unlike a normal encoder, a priority encoder assigns priority to the inputs – meaning if multiple inputs are active at the same time, the one with the highest priority will be considered in the output.
✨ What we will cover in this session:
🔹 Introduction to Priority Encoder
🔹 Working of 4x2 Priority Encoder
🔹 Example with step-by-step explanation
🔹 Truth Table of Priority Encoder
🔹 Logic Expressions and K-map simplification
🔹 Circuit Diagram / Implementation
🔹 Applications of Priority Encoder in real life
📌 Introduction:
An encoder converts active input lines into a coded binary output.
A priority encoder solves the problem of multiple inputs being active at the same time by assigning priority levels.
The input with the highest priority is encoded first.

📖 Description:
In this video, we explain Priority Encoder in Digital Electronics in a simple way. A priority encoder gives priority to the highest input when multiple inputs are active.
What’s Covered:
✅ Introduction to Priority Encoder
✅ 4x2 Priority Encoder with example
✅ Truth Table & Logic Expressions
✅ Circuit Implementation
✅ Applications in real life
🔹 Truth Table (4x2 Priority Encoder):
D3 → Highest priority, D0 → Lowest priority
If D3 = 1 → Output = 11
If D2 = 1 → Output = 10
If D1 = 1 → Output = 01
If D0 = 1 → Output = 00
Applications: Interrupt handling in microprocessors, keyboard encoding, robotics, and digital communication.
