Combining Boolean Operators (Edexcel GCSE Computer Science)

Combining Boolean Operators

• Boolean operators can be combined to produce more complex expressions

• The combination of two or more Boolean operators forms a logic expression

• Brackets are used to clarify the order of operations

• A logic diagram is a visual representation of combinations of Boolean operators within a logic circuit

• An example would be Q = NOT(A OR B)

• In the diagram above, the inputs are represented by A and B

• P is the output of the OR gate on the left and becomes the input of the NOT gate

• Q is the final output of the logic circuit

• This is a logic diagram for the Boolean expression Q = NOT(A OR B)

Example of combining Boolean operators

• P = (A OR B) AND NOT C
