Although computers are overwhelmingly digital today, there’s a good point to be made that analog computers are the more efficient approach for specific applications. The authors behind a recent paper ...

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.

Researchers at Cornell University have developed an electronic chip that they describe as a "microwave brain." The simplified chip is analog rather than digital, yet can process ultrafast data and ...

A SMALL Microsoft Research team has developed an analog optical computer (AOC) that uses light to solve complex optimization and AI problems, aiming for a device that is 100 times faster and 100 times ...

Microsoft Research has developed an analog optical computer (AOC) that uses light to solve complex problems. According to the team responsible for the project, which is based at the company's ...

Physicists have invented a new type of analogue quantum computer that can tackle hard physics problems that the most powerful digital supercomputers cannot solve. New research published in Nature ...

In a digital world, why bother with analog? Well, sometimes it can still be the right solution. Take, for instance, the analog multiplier (see figure). At its simplest, it’s a circuit that leverages ...
