Draw logic circuit for a converter that converts 4 bit binary input to its equivalent BCD number. 8m Jun2008
A four bit number can be any number value between 0 to 15 i.e. 0 to F in Hexadecimal.
BCD is a number which is represented in binary as a decimal number hence it can have a max of 9 number value in the representation and the number ranging from 10 to 15 will need two digits and their will be common value 1 in all number from 10 to 15.
