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. This works because‚ when adding two

CHAPTER 2 BINARY CODE 2.1 History of Binary Code: Binary numbers were first described in Chandashutram written by Pingala around 300 B.C. Binary Code was first introduced by the English mathematician and philosopher Eugene Paul Curtis during the 17th century. Curtis was trying to find a system that converts logic’s verbal statements into a pure mathematical one. After his ideas were ignored‚ he came across a classic Chinese text called I Ching or Book of Changes‚ which used a type of binary code. The
