In this lecture, we explain the Binary Coded Decimal (BCD) system, with a focus on the 8421 Code, also called Natural BCD. You’ll learn:

What is BCD and why it is used
Step-by-step representation of decimal digits (0–9) in 8421 BCD
Valid and invalid BCD codes
Difference between pure binary and BCD
Applications of BCD in calculators, digital clocks, and digital systems

From an exam perspective, remember: although many BCD codes exist (8421, 5421, 2421, Excess-3), when we say BCD Code, it usually refers to 8421 Code.

This lecture is part of our Digital System Design series, designed to make concepts easy and exam-ready.
