He’s solved that with a unique mechanical amplifier. Digital logic circuits generally have input power and ground connections in addition to their logic connection points, so [Thomas]’s main ...

A few simple selections configure this circuit for an application. The logic gate must operate from the desired supply voltage and provide adequate speed for the application. The delay components, R1 ...

You easily can add logic gates to your circuit to model computations ... expression that describes the truth table you defined. You can edit your circuit further by editing this equation directly. The ...

On the path to exploring complex logic ... input gate; the difference between the output and input voltages allows for some loss of signal and/or the addition of some noise into the equation.

Another plus of the featured circuit is the fact that it uses a 7486 IC for the XOR gate. Since this IC has 4 gates inside, the circuit can be expanded to build a four channel logic analyzer.

simple circuit to behave like any kind of logic gate. Such a chip could be transformed, for example, from a graphics card into a memory chip and back again – in just two computer clock cycles.

If a gate is active, it expresses a signal that directs the Cas9 to deactivate another gate within the circuit. In this way, the researchers can "wire" together the gates to create logical ...
