Convert Decimal Numbers to BCD and Gray Code

What is the process of converting decimal numbers to BCD and gray code?

How can we convert decimal numbers such as 547, 1051, and 137 to their BCD representation?

Answer:

The BCD (Binary Coded Decimal) representation of decimal numbers involves dividing the decimal number by 10 and converting the remainders to their 4-bit binary equivalent. The gray code conversion is achieved by converting the decimal number to binary and applying a specific algorithm to generate the gray code.

Converting decimal numbers to BCD (Binary Coded Decimal) and gray code involves specific steps and algorithms to represent the decimal values in binary format. Let's explore the conversion process:

Converting Decimal Numbers to BCD:

1. For the decimal number 547:

  • Divide 547 by 10: 547 ÷ 10 = 54 remainder 7
  • Convert the remainder 7 to its 4-bit binary representation: 0111
  • Divide 54 by 10: 54 ÷ 10 = 5 remainder 4
  • Convert the remainder 4 to its 4-bit binary representation: 0100
  • Continue this process until all digits are converted to their 4-bit binary form: 0101 0100 0111

2. For the decimal number 1051:

  • Divide 1051 by 10: 1051 ÷ 10 = 105 remainder 1
  • Convert the remainder 1 to its 4-bit binary representation: 0001
  • Divide 105 by 10: 105 ÷ 10 = 10 remainder 5
  • Convert the remainder 5 to its 4-bit binary representation: 0101
  • Continue this process until all digits are converted to their 4-bit binary form: 0001 0101 0000 0001

3. For the decimal number 137:

  • Divide 137 by 10: 137 ÷ 10 = 13 remainder 7
  • Convert the remainder 7 to its 4-bit binary representation: 0111
  • Divide 13 by 10: 13 ÷ 10 = 1 remainder 3
  • Convert the remainder 3 to its 4-bit binary representation: 0011
  • Continue this process until all digits are converted to their 4-bit binary form: 0001 0011 0111

By following these steps, you can convert decimal numbers to their BCD representation by converting each digit to its binary equivalent.

For gray code conversion, a specific algorithm is used to generate gray codes from binary numbers, providing a unique coding system beneficial in digital communication and error detection.
