MathsCasts: Karnaugh Maps for Two Variables
(Swinburne Commons, 2011)
In this screencast we look at how to set up a 2-variable Karnaugh map, followed by an example of simplifying a particular Boolean expression and simplifying its negation, using a 2-variable Karnaugh map.
MathsCasts: Negating and Simplifying Switching Circuits
(Swinburne Commons, 2011)
Given a diagram of a particular switching circuit, we start by identifying a Boolean function to represent it. We then find the negation of the switching circuit and finally, the simplest possible expression for it using ...
MathsCasts: Drawing Switching Circuits
(Swinburne Commons, 2011)
This screencast starts with a discussion of what it means for switches to be connected in parallel and in series in a switching circuit and how to draw each. Two examples are then given of how to draw circuits where there ...
MathsCasts: Designing Switching Circuits
(Swinburne Commons, 2011)
An example of using a truth table to determine a Boolean expression to represent a switching circuit, given certain specified conditions as to when current will flow through the circuit.
