It is possible to implement any combinational logic circuit using one type of logic gate. Such gates are the Nand and Nor gate and they are referred to a universal gate. This video shows why a Nand gate is regarded as a universal gate.﻿

This theorem is fundamental to logic and its application greatly assists in combinational logic circuit design.﻿

This video looks at a four variable Karnaugh Map and
shows how it is possible to plot a sum of minterms onto the map. Appropriate techniques are then applied to the plot on the map to show how the sum of minterms can be minimised.﻿

Here this video builds on the work of the previous video by showing examples of minimising expressions using a three variable Karnaugh Map. It also introduces a plot that cannot be used to minimise an expression.﻿
