BCD Adder

BCD Adder. BCD Adder. When the sum of two digits is less than or equal to 9 then the ordinary 4-bit adder can be used But if the sum of two digits is greater than 9 then a correction must be added “I.e adding 0110” We need to design a circuit that is capable of doing the correct addition.
