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 ...

The analog computer of decades-gone-by is something many of us younger engineers never got the chance to experience first hand. It’s pretty much a case of reading about them on these fine pages or ...

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 ...

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 ...

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 ...

(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, ...

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 first of three parts, Andy hypothesizes that the K2-W Analog Computer Op Amp’s design has some unrevealed mad science in its input-stage design. 1. K2-W Op Amp schematic from Bob Pease’s ...
