Our new tech editor for Analog looks at the evolution of “analog” and how it inadvertently spun off a pop music genre. Operational Amplifiers are exactly that—amplifiers that can perform mathematical ...

A computer that processes analog data is known as an analog computer. Analog computers store information in physical quantities in a continuous format and use measurements to perform computation.

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 ...

(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, ...

In the mid 1960's, an undergraduate friend invited me along to a lab where he had to run some “programs” on an analog computer. That sounded interesting. He set up his program with resistors and ...

Editor’s Note: This article came about from another article called “Circuits without wires” in which a comment by Arthur Glazar led to my discovery of this gem of an article, thanks to my colleague ...

Wanting to test the response curves on some analog parts, [Don Sauer] devised a way of using simple tools to graph analog tests on a computer. Here you can see the results of testing NPN, PNP, NMOS ...

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 ...

Very well researched and educational article - just by reading and watching the embedded clips I now know how a mechanical computer works and also a bit about fire control. I visited the HMS Belfast ...
