A subtractor can be designed using the same aproach as that of an adder ,subtractor are usually implemented within a binary adder for only a small cost when using the standard two's complement notation,by providing an addition/subtraction sector to the carry in and invert the second operand.

Construct BCD to excess3 code using full adder circuit?
4 full adders will be used BCD is a 4 bit code. Each bit of the BCD number will be an input of each full adder. input 1 in first FA. 1 in second and 0 in the last to FA's
