Understanding the Fundamentals of Analog Computing How Analog Computing Differs from Digital Analog computing stands apart ...

A computer that uses light rather than digital switches for calculations could help reduce the energy demands of artificial ...

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.

A device that processes infinitely varying signals, such as voltage or frequencies. A thermometer is a simple analog computer. As the temperature varies, the mercury moves correspondingly. A slide ...

The prototype is built from commercially available parts, including micro-LEDs, optical lenses, and sensors from smartphone ...

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 ...

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 ...

Microsoft has built a prototype computer that uses light and analog signals instead of traditional binary computing.

If you have had trouble with ordinary calculus, you may not be pleased to hear about “photonic calculus” — a recent idea from [Nader Engheta] of the University of Pennsylvania. The idea is that ...

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 ...

Recent progress on both analog and digital simulations of quantum fields foreshadows a future in which quantum computers ...
