A binary ____ adder is a device that takes ____ inputs A and B and ____ adds them together to create a sum and a ____. In a half adder there is no carry ____. It can easily be implemented using the logical inputs A and B and an ____ function as the ____ and an ____ gate as the carry out. This means it can only be used when adding two bits i.e. only the ____ bit in a binary sum. After the first bits are added all the other stages require the potential addition of a carry out from the ____ stage i.e. a carry in to this stage. To add two bits and a carry in we need to use a ____ adder. This uses two half bit ____ and ____ the carry out to make it function correctly. The sum and carry out can be generated from the ____ table and then simplified using ____. We are going to do this later in the lesson. Full adders can be ____ to add multiple bits together such as 2 ____.
