Argh. I got a test on Friday, and flip-flops are going to be on it. I still don't understand them. Can anyone explain to me how they work? Any links on the web? The book sucks at explaining them, and ...

Digital design with combinatorial gates like AND, OR, and NOT gates is relatively straightforward. In particular, when you use these gates to form combinatorial logic, the outputs only depend on the ...

Mechanical switches are pretty easy to understand—the contacts touch, the current flows, and Bob is, presumably, your uncle. But what about soft switches? Well, they’re not that difficult to ...

Now that we’ve introduced a JK flip-flop, let’s look at some circuits that we can create using it as the core element, including the T and D flip-flops. In my previous column, we started to look at ...
