Sinopsis

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online.In electronics, an adder or summer is a digital circuit that performs addition of numbers. In modern computers adders reside in the arithmetic logic unit (ALU) where other operations are performed. Although adders can be constructed for many numerical representations, such as Binary-coded decimal or excess-3, the most common adders operate on binary numbers. In cases where two''s complement or one''s complement is being used to represent negative numbers, it is trivial to modify an adder into an adder- subtracter. Other signed number representations require a more complex adder.
