Lesson details
Key learning points
- Boolean logic is the foundation of all digital circuit design.
- A logic circuit is a set of two or more logic gates that are connected to implement more complex logic.
- A digital electronic circuit in a computer system is typically made up of millions of logic gates.
Keywords
Logic circuit - a combination of two or more logic gates used to represent a more complex Boolean expression
Truth table - a table showing the outputs for all possible combinations of inputs to a logic gate or logic circuit
Common misconception
As logic gates are limited to two input, logic statements should also be limited in the same way.
Logic gates can be combined to created complex circuits that represent any number of logic statements combined.
