The 8421 code, also known as binary-coded decimal (BCD), is a way of encoding decimal numbers in a binary format. In this code, each digit of a decimal number is represented by its equivalent four-bit binary value, where the weights of the bits are 8, 4, 2, and 1. For example, the decimal number 25 is represented in 8421 code as 0010 0101, corresponding to the digits 2 and 5. This coding system allows for easy conversion between decimal and binary, making it useful in digital systems and applications.

Examples of weighted and non weighted codes?
Weighted codes assign different significance to each digit in a number representation, such as 8421 BCD code assigns weights of 8, 4, 2, and 1 respectively to each bit. In contrast, non-weighted codes like Gray code do not follow a positional weight pattern, where only one bit changes at a time when moving from one value to another to reduce errors in analog-to-digital conversion systems.
Is an invalid state in an 8421 BCD counter?
Yes, an invalid state can occur in an 8421 BCD (Binary-Coded Decimal) counter. The 8421 BCD representation can only encode decimal digits from 0 to 9, which corresponds to binary values from 0000 to 1001. Any binary representation from 1010 (A) to 1111 (F) is considered invalid in BCD, as it does not represent a valid decimal digit.
Why BCD called as 8421 code?
The BCD (Binary-Coded Decimal) is referred to as the 8421 code because it uses a specific binary representation where each decimal digit is encoded using four bits, with weights assigned to each bit in the order of 8, 4, 2, and 1. For instance, the decimal digit '5' is represented in BCD as 0101, which corresponds to 08 + 14 + 02 + 11 = 5. This weighted system allows for straightforward conversion between decimal and binary formats while ensuring each decimal digit can be distinctly represented.
How do you get the number eleven in math using the numbers 8421?
8 + 4 - 2 + 1 = 11
