Applications for using a single pushbutton to advance a circuit to its next logical state are legion. Typically, there are just “on” and “off” states, but there can be more. The heart of the circuit ...

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 ...
