Excess-3 code is known as self complimentary code why?
Excess-3 code is also known as self complementary, because it can easily be complemented(9's complement) to perform addition in the case of subtraction.

A self complementing code for Base-10 is a code for which the complement of a given encoded digit d[0-9] will result in 9-d, the 9's complement. To encode Base-10 numbers in… binary, we need to be able to represent 10 values [0-9] which means we require 4 bits because 3 bits can represent 8 values which is not enough; 4 bits can represent 16 values, which is more than we need, but we don't have (or want) fractional bits. There are numerous encoding schemes possible within these 4 bits, the most intuitive of which is the 8-4-2-1 scheme, or straight binary encoding of the decimal value. To encode 12 using 8-4-2-1, you would separately encode  and  as their respective binary representations  and . The 9's complement is relevant in the context of binary encoding decimal/Base-10 numbers because 9 is the largest value required when encoding Base-10 numbers. Your example implies Base-16, displayed as decimal, for which you are correctly generating the 15's complement rather than the 9's complement. 8-4-2-1 is intuitively a self complementing code for Base-16, because taking the complement of a 4 digit binary number is the same as subtracting it from 15. The same cannot be said for a Base-10 number represented the same way, because we are representing only 10 values in 16 member code space, which is why a number of more intricate systems have been devised to generate self-complementing codes for representation of decimal numbers in 4 digit binary numbers. Table 13.1 in the related link shows two self-complementing codes for decimal encoding, namely the 8,4,-2,-1 and excess-3 encoding schemes, and the subsequent section describes the purpose and theory behind self-complementing codes.
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 an…d 1's.
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.
The earliest known code of law was the Hammurabi code. It was the first laws codified together.
here we can't convert to any radix system.only one way adding 3 creates decimal system. Later we need convert what we want, in remaining radix systems we have weight/radix whi…ch tells that to convert to particular system directly.
Yes , it is a self complementry code but not a weighted code
Gray code:switching activity reduces due to which power consumption becomes less and speed can increase,for ex 7-0111 8-1000 above you can see switching takes place four time…s so that there is a problem for performance and power consumption.so in order to avoid thisproblem we r moving towards gray code. Excess 3 code:for hardware simplification
yes Excess- 3, 2421, 5211, 642-3, 84-2-1 self-complementing code
It is a way to represent values with a balanced number of positive and negative numbers. The primary advantage of XS-3 coding over BCD coding is that a decimal number can be n…ines' complemented (for subtraction) as easily as a binary number can be ones' complemented; just invert all bits.

Any self-modifying code will be practically impossible to debug, as problems would depend on the current state of the code when the bug occurred. Reproducing bugs would be… problematic. There may also be security risks or the risk of data corruption.
