In this video, we dive deep into the concept of Encoders, an important combinational circuit used in digital electronics. You’ll learn how 4-to-2, 8-to-3 encoders work, understand their truth tables, and how to derive output expressions from input data.

We also explore real-life applications of encoders and briefly touch upon the limitations of standard encoders, setting the stage for our next video where we’ll cover the Priority Encoder in detail!

📌 Topics Covered:

What is an Encoder?

4-to-2 Encoder design & logic

8-to-3 and Encoder explanation

Truth tables and Boolean expressions

Code conversion (Decimal to Binary)


Limitations of basic encoders
