The term BCD refers to representing the ten decimal digits in binary forms; which simply means to count in binary.
Code converter is a combinational circuit that translates the input code word into a new corresponding word. The excess-3 code digit is obtained by adding three to the corresponding BCD digit.
The Excess-3 BCD system is formed by adding 0011 to each BCD value. For example, the decimal number 7, which is coded as 0111 in BCD, is coded as 0111+0011=1010 in Excess-3 BCD.
