Derive a scheme for performing subtraction using BCD operands. Show a block diagram for the subtractor circuit.
Hint: Subtraction can be performed easily if the operands arein the 10's complement (radix complement) representation. Inthis representation,the sign digit is 0 for a positive number and 9for a negative number.
