Adders In Digital Electronics
Digital computers perform various arithmetic operations. The most basic operation, no doubt, is the addition of two binary digits. This simple addition of two binary digits. This simple addition consists of four possible elementary operations, namely,
The first three operations produce a sum whose length is one digit, but when the last operation is performed sum is two digits. The higher significant bit of this result is called a carry and lower significant bit is called sum.
There are two major types of adders
They are :
- Half Adder
- Full Adder
The logic circuit which performs addition of three bits is called as Full Adder.
