Logic gate simulator software

Boolean logic and logic gates

Introduction to logic circuit design

Logic statements and expressions

Creating logic circuits

Truth tables

Implementing Boolean logic in Python

In this unit pupils will discover that Boolean logic is a way of describing circuits inside a computer. They will recognise logic gates as the building blocks of processors. They will be able to construct logic diagrams, truth tables and simplify Boolean expressions.

Boolean logic

People who design computers use a {{}} to check the design of complex circuits before they are built out of expensive materials.

a physical device used to test logic gates

a software program that allows you to build and test logic circuits

a mathematical formula used to calculate the output of a logic gate

a physical representation of a logic circuit

a picture used to represent a logical statement

A logic gate simulator allows you to create an interactive {{}}.

What is the output of an AND gate when both inputs are False?

What is the output of an OR gate when one input is True and the other is False?

a logic gate that outputs True only if both inputs are True

a logic gate that outputs True if at least one input is True

a logic gate that outputs the opposite of its input

a table of all possible inputs and outputs for a logic gate or circuit

Which of the following is NOT a fundamental logic gate? 

In the truth table for (A AND B) OR C, what should the first column after the inputs be labelled as?

You can check that a circuit represents the logic you intended by drawing a {{}}.
