A thermometer is a simple analog computer. As the temperature varies, the mercury moves correspondingly. A slide rule is another example. Although special-purpose, complex analog computers are ...

pushing a digital system to be more precise than the physical quantization or to work faster than an analog computer is very difficult. A few resistors and op-amps are cheap and simple.

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 ...

The world is digital, but sometimes the power of analog is just what is needed. The analog multiplier is a case in point with ...

In the 1930s, the Russian scientist Vladimir Lukyanov built an analog computer known as the "Water Integrator" or "Lukyanov's Integrator." This computer was built to solve partial differential ...
