Describing the behaviour of logic circuits featuring more than one gate.

Learning objectives

  • Behaviour gates with more than two inputs
  • Using truth tables to describe combinations of gates


Presentation. Introduces the idea of a gate with more than two inputs, using a 3-input AND gate as an example. Shows how a 3-input gate can be created from two 2-input gates. These ideas are explored more in the workbook.

Also includes a PDF workbook with notes and solutions. Covers symbols and truth tables of normal and inverting gates, 3-input variants of different gates, and how to use truth tables to analyse combined gates
