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 ...

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 ...

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 ...

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 ...

Researchers at Cornell University have developed an electronic chip that they describe as a "microwave brain." The simplified chip is analog rather than digital, yet can process ultrafast data and ...

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 ...

The distinction between analog and digital signals is very simple, but it can still be a challenge to wrap one's mind around the concepts that define the two systems. Just when you think you've got it ...
