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 [1] and [2] as their respective binary representations [0001] and [0010]. 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.

# What is meant by self complementing binary 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.

# What is self complementary code?

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.

# What is the oldest known law code?

The earliest known code of law was the Hammurabi code. It was the first laws codified together.

# Why is an excess-3 code is called an unweighted code?

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.

# Is 8421 self complementary code?

Yes , it is a self complementry code but not a weighted code

# What are advantages of gray code and excess-3 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.

# What is the application of excess 3 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.
