Including XOR gates in your functions offers significant benefits by reducing transistor and track counts and increasing testability. As designers, we're used to representing digital functions using ...

Good Grief Charlie Brown! Ever since I presented the “Black Box Brain Boggler” in myLogically Speaking column in the 8th May issue of EE Times, I've been running around in ever-decreasing circles ...

The fun part about logic gates is that there are so many ways to make them, with each approach having its own advantages and disadvantages. Although these days transistor-transistor logic (TTL) is the ...

Before we plunge headfirst into the fray with gusto and abandon (and aplomb, of course), let’s remind and reassure ourselves that—although the following discussions focus on the devices and ...

I've covered tons of different scientific applications you can run on your computer to do rather complex calculations, but so far, I've not really given much thought to the hardware on which this ...

To demonstrate how computers work, [Alex Gorischek] has made a physical example of how binary logic gates work using pulleys and weights. For anyone who doesn’t know much about logic gates (Wikipedia) ...
