Now you have learnt logic gates we will take a look at how they are combined inside hardware. You may well be asked in an exam to draw your own logic gates or to work out what a combination of logic gates will output. In this section we will look at the best way to describe what a set of logic gates is in boolean algebra. Let's take a look at a quick example:
Exercise: Logic gate combination outputs For the following logic gate combinations work out output Q for each: Answer:
Answer:
