Ghate RAIT Navi-Mumbai snghate23@gmail. com ABSTRACT The primary advantage of XS-3 coding over BCD coding is that a decimal number can be nines ’ complemented (for subtraction) as easily as a binary number can be ones ’ complemented ; just invert all bits. In addition‚ when the sum of two XS-3 digits is greater than 9‚ the carry bit of a four bit adder will be set high
