The use of a single byte (8-bits) to store or display two BCD digits, allowing a byte to hold a BCD number in the range of 00 - 99, is known as packed BCD. Standard binary coded decimal code is commonly known as a weighted 8421 BCD code, with 8, 4, 2 and 1 representing the weights of the different bits starting from the most significant bit (MSB) and proceeding towards the least significant.

Code Converters - BCD (8421) to/from Excess-3 Read Courses Prerequisite - Number System and base conversions Excess-3 binary code is an unweighted self-complementary BCD code. Self-Complementary property means that the 1's complement of an excess-3 number is the excess-3 code of the 9's complement of the corresponding decimal number.

(324)10 -> 0011 0010 0100 (BCD) Again from the truth table above, 3 -> 0011 2 -> 0010 4 -> 0100 thus, BCD becomes -> 0011 0010 0100 This is how decimal numbers are converted to their equivalent BCDs. It is noticeable that the BCD is nothing more than a binary representation of each digit of a decimal number.

Similar to the BCD or 8421 code, the 2421 code is another type of weighted code used in digital systems. This code measures the positional weights as 2 4 2 1. The following table gives the decimal numbers and their corresponding 2421 codes. 2421 Code Table:

The 2421, the excess‐3 and the 84-2-1 codes are examples of self‐complementing codes. Such codes have the property that the 9's complement of a decimal number is obtained directly by changing 1's to 0's and 0's to 1's (i.e., by complementing each bit in the pattern). For example, decimal 395 is represented in the excess‐3 code as 0110 1100 1000.

What is BCD? and 8421 code? Explained in Tamil Middle Class
BCD Code. BCD code is an abbreviation for Binary coded Decimal codes. It is a numeric weighted code, in which each digit of a decimal number is represented by a separate group of 4-bits. There are several BCD codes like 8421, 2421, 3321, 4221, 5211, 5311, 5421, etc. The most common and widely used BCD code is 8421 code.
Digital logic circuit foundation two decimal code (BCD code
As stated earlier, both 8421 and 2421 are weighted codes, where each decimal digit can be found from its code word by assigning a fixed weight to each code word bit. For example, the weights of four bits of 8421 code are 2 3, 2 2, 2 1, and 2 0. So, decimal digit 5 in 8421 is "0101", which is 0 x 2 3 + 1 x 2 2 + 0 x 2 1 + 1 x 2 0 = 5.

That is, the BCD representation of the decimal number 368 could be given as 0011 0110 1000. BCD, but we will (in this lesson) ensure that the use of BCD representation is clear by context and will not employ that notation . Example: Compare the binary representation of the decimal number 843 to the 8421 BCD code for that number. Solution:
Solved Q). Design a code converter that converts BCD code to
For the actual. Design an 8421 BCD to 2421 BCD converter circuit. The truth table as follows: Note that input combinations of 1010 to 1111 can be treated as "don't cares". Generate the logic equations for each of the 4 output bit s. For the actual circuit implementation, you are restricted to using the 74LS small scale logic integrated circuits.
