About this video
AQA Specification Reference
AS Level 3.6.4.1
A Level 4.6.4.1
This video illustrates how the different permutations of zeros and ones applied to logic gates and their output can be recorded in what is known as a “truth table”. It also shows how these truth tables relate to their corresponding logic gate symbols.
- What are the logic gate symbols and associated truth tables for the following Boolean terms:
1. NOT
2. AND
3. OR
4. XOR
5. NAND
6. NOR
