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.

MRNA is made of 3letter code words called?
The three letter code words are called codons.
What is a DNA code for one hereditary trait is called?
The DNA code for one hereditary trait is called a gene.
What part of DNA provides the code for proteins?
The parts of DNA that code for proteins are called genes.
Are sections of chromosomes that code for a trait?
Sections of chromosomes that code for a trait are called genes.
A segment of DNA that provides the code for creating protein molecules is called what?
They are called sense DNA. On the other hand, portions which do not code for proteins are called junk DNA or non-sense DNA.
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.
What are the 4 an invalid BCD code?
BCD code isn't valid for these integers , 10 , 11 , 12 , 13 , 14 i.e if these integers ae converted to binary code they 'd be called wrong BCD
Why bcd called as 8421code?
BCD, or Binary Coded Decimal, is called 8421 code because it represents each decimal digit using a 4-bit binary number, where the weights of the bits correspond to the binary values of 8, 4, 2, and 1. In this encoding system, the four bits are assigned values based on their position, allowing for the unique representation of decimal digits 0 through 9. The name "8421" reflects the specific weights assigned to each bit, facilitating easy conversion between decimal and binary formats.

Why is BCD code called a weighted code?
A: A Binary code represent a binary number 0.1.2.4.8. etc. that is why it is called a weighted number
What is the difference between weighted and non weighted codes?
what is weighted codes: The decimal value of a code is obtained summing up the positional values. weghted binary code s are those which obey positional weighting principle. each position of number represents a specific weight. There are millions of weighted code The most common one is 8421 Non weighted codes: This codes are not positionaly weghted. each position with in the binary no is not assgned to afixed value.Examples of nonweghted code is ASCCI, GREY CODE, EBCDIC CODE etc
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 8421 self complementary code?
Yes , it is a self complementry code but not a weighted code
What is a 4 BCD code?
A 4 BCD code is a 4 decimal-digit BCD code, thus a 16 digit binary-code. You take the decimal number 3545. It's BCD code is 0011 0101 0100 0101 where every 4 bits represent a decimal digit.
What does a BCD invalid code detector do?
detects the invalid portion of the bcd number codes (1010-1111)
How i can Design a BCD-to-excess-3 code converter with a BCD-to-decimal decoder and four OR gates?
i dont know 1001+1001 - Constructing a BCD-to-excess-3-code converter with a 4-bitt adder we know that the excess-3 code digit is obtained by adding three to the corresponding BCD digit. To change the circuit to an excess-3-to-BCD-code converter we feed BCD-code to the 4-bit adder as the first operand. Then feed constant 3 as the second operand. The output is the corresponding excess-3 code. To make it a BCD to excess-3 converter, we feed the 2's complement of 3 as the second operand. - Constructing a BCD-to-excess-3-code converter with a 4-bitt adder we know that the excess-3 code digit is obtained by adding three to the corresponding BCD digit.
