One of the first things we learn about computers is the concept of binary ones and zeroes. When we dig into implementation of digital logic, we start to learn about voltages, and currents, and other ...

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 ...

An analog computer is a system that provides information in continuous form. These computers can only represent physical quantities such as pressure, weight, voltage pressure, speed, and more.

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 ...

A new study shows that metamaterials can be designed to do "photonic calculus" as a light wave goes through them. A light wave, when described in terms of space and time, has a profile that can be ...

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 ...

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 ...

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 ...
