84-2-1 self-complementing code
no
If the one's complement of the code is equal to the nine's complement of the code, then it is called a self complementing code.
9
a binary code is self complementary if complement of any code word is again a code .in self completing codes 9's complement of a number can be obtained by interchanging 0's and 1's.
A self complementing code is one thats 9's complement in decimal is the 1's complement in binary.Ex: The 9's complement of 7 is 2 in decimal. In 2421 code, and .
9's complement of a decimal number represented in 2421 code is easily obtained by replacing the 1s with 0s,and 0s with 1s,so 2421 code is called a self complementing code.example-2421 of '2' is '0010',after replacing the 0s with 1s and 1s with 0s weget '1101' which is the 2421 of '7'(9s complement of 2 is 7). Thus 2421 code is self complementary.
characteristic of Gray code
One disadvantage of Gray code is that it is not as intuitive for human understanding compared to binary code. Another drawback is that Gray code is not as efficient in terms of mathematical operations, such as addition and subtraction, compared to binary code. Additionally, Gray code requires more bits to represent the same range of values as binary code, which can result in increased complexity and storage requirements.
Magnificent and marvelous are complementing words. Mighty and modest are complementing words.
The Gray Code is a type of binary code developed by a programmer named Frank Gray. Gray code is a binary numeral system that differ than normal binary code, and is used widely to detect errors in software.
You're good at complementing them, and it's usually code for "I like you, too."
The airport code for Gray Army Airfield is GRF.
