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, ...

We are somewhat spoiled because electronics today are very reliable compared to even a few decades ago. Most modern electronics obey the bathtub curve. If they don’t fail right away, they won’t fail ...

This circuit uses electromechanical relays to retain its state indefinitely, even when power is off. It consumes no power except when triggered from one state to the other. Many varieties of ON/OFF ...

In this paper, the authors deal with the testable design of conservative logic based sequential circuits by using two test vectors. The conservative logic based sequential circuits are built from the ...

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 ...
