Decimal 30 = binary 11110. The decimal binary code (BCD), however, is 11 0000.
Binary Coded Decimal (BCD) is a set of coding systems for storing decimal digits in binary code. There are several such codes, I will give examples of 3: straight BCD, XS3 BCD, and 2 of 5 BCD. Straight BCD uses the actual binary value of the decimal digit value: 0 = 0000 1 = 0001 2 = 0010 3 = 0011 4 = 0100 5 = 0101 6 = 0110 7 = 0111 8 = 1000 9 = 1001 XS3 BCD adds 3 to the binary value of the decimal digit value to make the code: 0 = 0011 1 = 0100 2 = 0101 3 = 0110 4 = 0111 5 = 1000 6 = 1001 7 = 1010 8 = 1011 9 = 1100 2 of 5 BCD uses a 5 bit code where only 2 bits can be on in a decimal digit's code: 0 = 00011 1 = 11000 2 = 10100 3 = 10010 4 = 10001 5 = 01100 6 = 01010 7 = 01001 8 = 00110 9 = 00101
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
BCD refers to Binary Code Decimal there are no diagrams it is just a numbers system GRAY code is a means to make one reliable state to change at a time eliminating false coding because of transitions in counters and such
the first time write the binary coded decimal as input write its truth tablle to nine and after nine put the all position dont care to number fifteen same is also for excess three write its truth table to 9 and from 9 to 15 dont care then simplifiy each output coloumn by K_MAp to find out th circiut
BCD is a decimal number. BCD is one specific way to store decimal numbers in computer memory.
BCD of 862 is 100001100010
41 in decimal is 0100 0001 in BCD (this is 8 bits not 6 bits)41 in decimal is 101001 in binary (this is 6 bits, but binary not BCD)There is no 6 bit BCD representation of the decimal number 41!
BCD is used for binary output on devices that only display decimal numbers.

BCD (Binary Coded Decimal) output can be generated using decimal-to-BCD conversion algorithms. One common method involves dividing the decimal number by 10 and storing the remainder as the Binary Coded Decimal digit. This process is repeated until all decimal digits are converted into BCD form. Alternatively, some microcontrollers have built-in instructions to directly convert decimal numbers to BCD format.
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.
The decimal number 10, represented in BCD is 0001 0000. If, instead, you mean that you have 10 in BCD and want to know what that means, that is equivalent to 0000 0010 and would be 2 in decimal.
It is 0001 0110 0011.
