Why is it called 8421 code?
The BCD8421 code is so called because each of the four bits is given a ‘weighting’ according to its column value in the binary system. The least significant bit (lsb) has the weight or value 1, the next bit, going left, the value 2. So the 8421BCD code for the decimal number 610 is 01108421.
What is the decimal equivalent of 1010 in 2421 code?
Gray Code

What is the meaning of 2421 code?
2421 code is another BCD code. It is weighed code. For example, 6 is 1100 and 3 is 0011. The gray code is a binary code. The binary bits are arranged in such a way that only one binary bit changes at a time when we make a change from any number to the next.
What is the 2421 equivalent of 786?
Let us find the 2421 equivalent of the decimal number 786. This number has 3 decimal digits 7, 8 and 6. From the table, we can write the 2421 codes of 7, 8 and 6 are 1101, 1110 and 1100 respectively.
What is the difference between 2421 code and Gray code?
2421 code is another BCD code. It is weighed code. For example, 6 is 1100 and 3 is 0011. GRAY Code. The gray code is a binary code. The binary bits are arranged in such a way that only one binary bit changes at a time when we make a change from any number to the next. Gray code is reflected code.
What is the difference between 0-4 and 5-9 in 2421 code?
The numbers 0–9 in 2421 code are represented in such a manner that numbers 0–4 have a 0 in the first bit and are represented the same as in common BCD, while numbers 5–9 have a 1 in the first bit and are determined by : n – (2 * first_digit).
