7. The AND gate

The next type of logic gate also has two inputs as shown below

two input gate

The logic will handle both inputs at the same time and create one output. The AND gate has this logic

  • If input A and input B is 1 then the output is also 1

This is a table showing every possible input and output

the or table

As you can see, if both A and B are 1 then the output is also 1 otherwise it is 0.

The standard way of drawing an AND gate is shown below

the OR gate symbol
