Logic Circuits into Logic Expressions
Logic gate circuits can be expressed as a circuit diagram, or as a written logic expression (sometimes known as a logic statement).
e.g. Z = ((NOT A) AND (A OR B)) OR (A OR B)
Each exam board will have their own preference on how to write a logic expression, but the principles remain the same.
Our Logic Circuits page explains how to create truth tables for logic circuit diagrams.
Our Logic Expressions into Truth Tables page explains how to complete a truth table from a logic expression.
Our Logic Gates page explains all about the individual logic gates.
How to create a written logic expression from a logic circuit diagram
The video below takes you step by step through the process of turning a logic circuit diagram into a written logic expression.
