Understanding BCD and Excess-3 | BCD to binary conversion | Excess-3 to binary conversion | DE.06

This video tutorial explores different binary codes used to represent numbers, focusing on BCD and Excess-3 codes. BCD, or Binary Coded Decimal, is a simple code where each decimal digit is represented by its binary equivalent. Excess-3 code is derived by adding three to each BCD digit, making it a self-complementing code. The video explains the representation of numbers in these codes and highlights their unique properties. The tutorial concludes with a preview of the next topic, Grey Code.
