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 ...

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 ...

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 ...

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 ...

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 ...
