This is a list of examples of early computation devices considered precursors of the modern computers. Some of them may even have been dubbed 'computers' … See more

Analog computers often have a complicated framework, but they have, at their core, a set of key components that perform the … See more

In the 1950s to 1970s, digital computers based on first vacuum tubes, transistors, integrated circuits and then micro-processors became more economical and precise. This led digital computers to largely replace analog computers. Even so, some research … See more

The similarity between linear mechanical components, such as springs and dashpots (viscous-fluid dampers), and electrical components, such as See more

Analog computing devices are fast; digital computing devices are more versatile and accurate. The idea behind an analog-digital hybrid is to combine the two processes for the … See more

Mechanical analog computers
While a wide variety of mechanisms have been developed throughout history, some stand out because of their theoretical importance, or … See more

In general, analog computers are limited by non-ideal effects. An analog signal is composed of four basic components: DC and AC … See more
