4 full adders will be used BCD is a 4 bit code. Each bit of the BCD number will be an input of each full adder. input 1 in first FA. 1 in second and 0 in the last to FA's
Yes , it is a self complementry code but not a weighted code
check this link for the code:http://www.dnatechindia.com/index.php/Code-Library/8051_ASSEMBLY/12-bit-HEX-to-BCD-Convertor.htmlhttp://www.dnatechindia.com/index.php/Code-Library/8051_ASSEMBLY/8-bit-HEX-to-BCD-convertor.htmlA: The conversion is simple really a group of FOUR bits are usually the best method to simplify a BCD of four bits in hexadecimal. Example 1111 is just written F If it was written in octal the bits will be 3 as 111 or 7. As BCD becomes longer and longer these two methods were used to simplify the code a128 bits in BCD will be 8 zeros and ones or simply FF in octal notation it becomes 277
BCD is a decimal number. BCD is one specific way to store decimal numbers in computer memory.
