Logic gates are the bricks and mortar of digital electronics, implementing a logical operation on one or more binary inputs to produce a single output. These operations are what make all computations ...

One of the hardest things about studying electricity, and by extension electronics, is that you generally can’t touch or see anything directly, and if you can you’re generally having a pretty bad day.

Nanotech systems based on DNA may be on the verge of becoming very large and complex, if not immediately useful to medicine or manufacturing. Researchers have combined simple strands of DNA into the ...

Researchers have built logic circuits, the heart of all electronic gadgets, on molybdenum disulfide films that are two molecular layers thick (Nano Lett., DOI: 10.1021/nl302015v). The devices are the ...

The previous article examined the concept of logic gates. They can be made from discrete and active electronic components, although today logic gates are available within integrated circuits. In this ...

The circuit shown is a 3-input Resistor-Transistor Logic (RTL) gate. a. Write the truth table for the input combinations of 0V and 5V with respect to the ground. b. Based on the output from the truth ...

I've covered tons of different scientific applications you can run on your computer to do rather complex calculations, but so far, I've not really given much thought to the hardware on which this ...
