Illogical Logic Part 1 - Boolean Algebra Paul Clarke Electronics Design Engineer When it comes to logic, we know it’s all supposed to make sense. For newcomers, it can also be very confusing to wrap your head around these concepts. This is why I have decided to do a short series on understanding the illogical world of logic! For the most part, understanding basic logic gates is easy enough. They explain what they are clearly; an AND gate just says the output is: logic ‘1,’ then input ‘x’ AND ‘y’ are logic ‘1.’ If you’re not 100% on this and other logic gates, then a quick read on Wikipedia will help set you straight. What becomes confusing is that we use lots of logic gates together, like in an FPGA. So, how do you work out what you need and why do some people seem to use so few gates for such complex tasks? Boolean algebra is a way of explaining logic in a written form without having to draw out all the logic gates. In place of an AND gate, you simply write A.B (note the full stop), and for the OR function you use the plus symbol (for example: A+B). This means you can turn complex logic into one written line of Boolean (Figure 1). What’s shown in Figure 1 quickly becomes… However, Boolean allows you to do things you cannot see or work out from a logic circuit. Boolean allows you to apply simple rules that will enable you to break down the logic to simply the elements that matter. <strong>EEWeb</strong> | Electrical Engineering Community Visit www.eeweb.com 17
