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.

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 ...

This analog computer can multiply ... zeroed out and read the value that knob is pointing to. It seems much more simple than some of the discrete logic computers we’ve seen, yet it’s just ...

simple analog filters; power transfer and impedance matching; op amps realizing active filters; signal spectra and the Fourier transform; signal sampling and aliasing; bandwidth and channel capacity; ...

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 ...
