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 “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 ...

Conventional computers process and store information using separate components, known as a processor and memory unit. Because ...

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 ...

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 ...

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 ...

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 ...

(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, ...

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 ...

[Janis Alnis] wanted to build an analog computer circuit and bought some multiplier chips. The first attempt used apparently fake chips that were prone to overheating. He was able to get it to work ...
