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.

Hardware interfaces that accept non-digital signals. For decades, all the plugs and sockets on traditional audio and video equipment connected analog lines. In addition, the common high-density DB-15 ...

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 ...

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 ...

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 ...

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 ...

Your design task, should you decide to accept it: given an input voltage, square it. Ok, that’s too hard since squaring 8 volts would give you 64 volts, so let’s say the output should be 10% of the ...

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 ...

The standard analog input for a PC monitor is the Video Graphics Array connection. As technology has developed, many PC monitors have been manufactured accommodate multiple input standards. While VGA ...
