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 ...

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 ...

Analog computers are systems that perform computations by manipulating physical quantities such as electrical current, that map math variables, instead of representing information using abstraction ...

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 ...

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 ...

Forward-looking: Microsoft is working on a novel, future-proof computer design that could sidestep Moore's law. The system, known as Analog Iterative Machine (AIM), is an analog optical machine that ...
