Analog computers have been used extensively in the past, for things like tide calculations, but in the semiconductor era things have mostly gone digital. Even where you have analog elements, like DRAM ...

Could updated analog computer technology – popular from about 1940-1970 –be developed to build high-speed CPUs for certain specialized applications? Researchers at the Defense Advanced Research ...

When your only tool is a hammer, everything starts to look like a nail. That’s an old saying and perhaps somewhat obvious, but our tools do color our solutions and sometimes in very subtle ways. For ...

Creation of a single-chip analog/hybrid computer reveals that special analog versions of computers could be used to solve complex problems such as nonlinear differential equations. Just recently, I ...

Life, uh, finds a way. And more often than not, that way is analog, not digital. Even the impulse-like action potentials in the brain are more complex than computers’ 1s and 0s — and digital ...

See refrigerator-esque and semi-trailer-sized models, including an early mobile computer. The Vintage Computer Festival East is a once-a-year museum exhibit in Wall, New Jersey that shows off vacuum ...

As requested by readers, editor Andy Turudic demonstrates that it’s child’s play to set up an Analog Computer to compute a Lorenz Attractor. Anabrid’s THAT Analog Computer provides a flexible, ...

I was doing some reminiscing about my college days and comparing to what is being taught today. One of the things that I clearly see is that schools focus more on the digital side of electronic design ...

The discovery of DNA was one of the most important scientific events of the twentieth century, revealing the instructions which make up every single living thing on Earth. However, more recently ...

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 ...

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 ...

We are always impressed with something so simple can actually be so complex. For example, what would you think goes into an analog computer? Of course, a “real” analog computer has opamps that can do ...
