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 ...

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 ...

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 ...

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, ...

On the edge: calculations show how the acoustic system could be used to detect the edges of an image comprising the letters "EPFL" A compact analogue computer based on an acoustic metamaterial has ...

When old tech dies, it usually stays dead. No one expects rotary phones or adding machines to come crawling back from oblivion. Floppy diskettes, VHS tapes, cathode-ray tubes—they shall rest in peace.

Today, most of what we think of as a computer uses digital technology. But that wasn’t always the case. From slide rules to mechanical fire solution computers to electronic analog computers, there ...

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 ...

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 ...

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 ...

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 ...
