Our new tech editor for Analog looks at the evolution of “analog” and how it inadvertently spun off a pop music genre. Operational Amplifiers are exactly that—amplifiers that can perform mathematical ...

A “cheap as chips” open-source Analog Computer can run circles around a Raspberry Pi in solving differential equations and for simulating natural phenomena. To keep costs down, the Anabrid team ...

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 ...

Early computers could perform fairly complex calculations just by arranging a few analog circuits. By choosing appropriate resistor and capacitor values, arithmetic summers, integrators, and ...

(Nanowerk Spotlight) The pursuit of faster and more efficient computing has been a driving force in technological progress for decades. As the demand for computational power continues to grow, ...

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 ...

Microsoft has built a prototype computer that uses light and analog signals instead of traditional binary computing. The system, developed in Cambridge, U.K., is designed to handle optimization tasks ...

In the azure waters off the coast of Antikythera, Greece, a chance discovery in the early 20th century transformed our understanding of ancient technology. A sponge diver, exploring the remnants of a ...

Computing today is digital, but analog has a future. Exponential advances in digital hardware have both driven and benefited from the rise of artificial intelligence (AI), but its escalating energy ...
