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 ...

I'm trying to help my son understand flip-flops. He's home from Uni for holiday and has a "workbook" to get thru all about Logic Circuits and Boolean algebra etc. Between us we've been able to ...

Figure 1 gives a simple circuit for the PUSH ON, PUSH OFF function with only a few inexpensive components. In this design, the output is connected to the input of the gadget when you press the push ...

A flip-flop is one of the most basic digital electronic circuits. It can most easily be built from just two transistors, although they can and have been built out of vacuum tubes, NAND and NOR gates, ...

Many varieties of ON/OFF control circuits use some form of flip-flop that responds to a pushbutton switch or other control input. These all have volatile memory and default to an OFF condition if ...

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 ...

An electronic circuit that maintains its 0 or 1 state and is used in static memories and hardware registers. By the mid-20th century, the flip-flop was a breakthrough in circuit logic, which allowed ...

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 ...
