Well, let's think about BCD, or Binary Coded Decimal, in a calm and happy way. An advantage of BCD is that it's easy for humans to read and understand because it represents each decimal digit with a 4-bit binary code. However, a disadvantage is that it's not as efficient for computers to process compared to pure binary representation. Just remember, every technique has its own beauty and purpose in the world of digital art!
BCD code isn't valid for these integers , 10 , 11 , 12 , 13 , 14 i.e if these integers ae converted to binary code they 'd be called wrong BCD
234 in BCD is 0010 0011 0100
Decimal: 3 2 5 Binary: 0011 0010 0101 so 325 = 0011 0010 0101
A BCD digit only uses the binary patterns that represent decimal numbers, ie 0000 - 1001; this requires 4 bits (1 nybble) so there can be 2 BCD digits to a byte. Therefore in 3 bytes there can be 3 × 2 = 6 BCD digits. The largest BCD digit is 1001 = 9. Assuming non-signed, the maximum 3 byte BCD number is 999,999.
Example Binary 00111000 Convert to Decimal 56 Convert to BCD by using groups of four binary numbers for each digit 5 6 0101 0110
Write a program to convert a 2-digit BCD number into hexadecimal
WRITE A PROGRAM TO CONVERT A 2-DIGIT bcd NUMBER INTO HEXADECIMAL
In BCD each digit of a decimal number is coded as a separate 4 bit binary number between 0 and 9.For example:Decimal 12 in BCD is shown as 0001 0010 (Binary 1 and Binary 2), in Binary it is 1100.
In BCD it is 00100111 In Binary, which is what you mean, it is 101111
BCD is used for binary output on devices that only display decimal numbers.
Write a program to convert a 2-digit BCD number into hexadecimal
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!
Binary coded decimal (BCD) is easier to convert between displayed or printed form than is pure binary.
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.
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
A: A Binary code represent a binary number 0.1.2.4.8. etc. that is why it is called a weighted number
