A computer that processes analog data is known as an analog computer. Analog computers store information in physical quantities in a continuous format and use measurements to perform computation.

The analog computer of decades-gone-by is something many of us younger engineers never got the chance to experience first hand. It’s pretty much a case of reading about them on these fine pages or ...

When your only tool is a hammer, everything starts to look like a nail. That’s an old saying and perhaps somewhat obvious, but our tools do color our solutions and sometimes in very subtle ways. For ...

Analog computers were largely phased out once digital systems began to hit the scene, but they’re still used in certain situations because they’re well-suited to complex simulations. Now, a research ...

A new study shows that metamaterials can be designed to do "photonic calculus" as a light wave goes through them. A light wave, when described in terms of space and time, has a profile that can be ...

While digital computers have become entrenched in our daily lives, a new analog quantum computer offers a stark contrast in both its design and capabilities. A team of physicists from Stanford ...

In 1961, the best general purpose desktop computer money could buy was the Pace TR-48. At just 400 pounds and $25K, the only downside was that it was a little tough to program. That's because the ...

An analogue computer chip can run an artificial intelligence (AI) speech recognition model 14 times more efficiently than traditional chips, potentially offering a solution to the vast and growing ...

(Nanowerk News) The field of metamaterials has produced structures with unprecedented abilities, including flat lenses, invisibility cloaks and even optical "metatronic" devices that can manipulate ...
