🧠 Special Conversions Explained

Gray Code

Used in digital systems to reduce errors by ensuring only one bit changes at a time.

BCD (Binary Coded Decimal)

Each decimal digit is represented using 4-bit binary, commonly used in displays and financial systems.

Excess-3

A biased code where 3 is added to each decimal digit before binary conversion, useful in digital arithmetic circuits.
