    Bcd adder

    BCD addition is the same as binary addition with a bit of variation: whenever a sum is greater than 1001, it isnot a valid BCD number, so we add 0110 to it, to do the correction. This will produce a carry, which is added

    to the next BCD position.

    Add the two 4-bit BCD code inputs.

    Determine if the sum of this addition is greater than 1001; if yes, then add 0110 to this sum and

    generate a carry to the next decimal positi
