The counting of gray codes is somewhat different from others as its digits has a difference of only 1-bit as of next number that is the reason it is also called unit-distance code.

Gray codes are also non-weighted codes as its value is not dependent on any weights. It is defined as the increment of 3 in its binary units when converted from any other number system.ĩ is a decimal number which is written as 1001 in binary and on adding 0011, it is converted into 1100 which become an excess-3 code. Some of the non-weighted codes are as follows:Įxcess-3 are non-weighted codes which are also called biased representation. The value of any representation can be calculated by multiplying each bit from LSB with the increasing power of 2. Non-weighted codes are those binary representation which are independent of positional weighting. Every representation is a 4-bit binary number which defines the value of a single decimal number, i.e. The weight of the position of these codes are 2, 4, 2 and 1 from MSB to LSB. The value of the binary representation is defined by the sum of multiplication of weight and the binary digit of that position. The weight of the position are 6, 3, 1 and 1 respectively from MSB to LSB. Its weight of the position are 8, 4, 2 and 1 from MSB to LSB. Some of those codes are discussed as below:īinary coded decimal are the codes in which the value of the representation is the sum of weights defined by the position. Weighted codes are those binary representation in which every bit has a certain weight depending upon their specific position. There are many types of binary codes used in digital number system which are similar to each other but each have individual significance while using them in digital electronics.
