What we have learnt
- The Binary Coded Decimal (BCD) represents decimal digits and allows easy conversion between binary and decimal forms.
- Excess-3 code simplifies arithmetic operations by adding 3 to each decimal digit, making it useful in various calculations.
- Gray code minimizes errors in digital systems as successive values differ by only one bit.
Key Concepts
- -- Binary Coded Decimal (BCD)
- A method of encoding decimal numbers in binary form, where each digit of the decimal number is represented by its four-bit binary equivalent.
- -- Excess3 Code
- A type of binary-coded decimal in which each decimal digit is represented by its binary equivalent after adding three to it, simplifying certain arithmetic operations.
- -- Gray Code
- An unweighted binary code where two successive values differ by only one bit, reducing the likelihood of errors during transitions.
