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.

Today, most of what we think of as a computer uses digital technology. But that wasn’t always the case. From slide rules to mechanical fire solution computers to electronic analog computers, there ...

The concept of optical computing is reintroduced with an important new twist — optical computing not as a digital machine, but as an analog engine able to serve as a hardware accelerator for existing ...

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 ...

Editor’s Note: This article came about from another article called “Circuits without wires” in which a comment by Arthur Glazar led to my discovery of this gem of an article, thanks to my colleague ...

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 ...

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 ...

Could updated analog computer technology – popular from about 1940-1970 –be developed to build high-speed CPUs for certain specialized applications? Researchers at the Defense Advanced Research ...
