This is going to be a column that’s divided into three sections. It’s based on a question that a student posed in the EEWeb forums, and he also sent it directly to yours truly. The core of this ...

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 ...

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 ...

Spin waves can be applied to low-power multi-input-multi-output logic gates based on its wave functionality realized without electron travelling. In particular, spin waves propagating in yttrium iron ...

What’s the weirdest computer you can think of? This one’s weirder. [Dr. Cockroach] figured out a way to create an inverting NOT gate from just one LED and two resistors (one being a photo-resistor).
