Analogb> computer - Wikipedia, the free encyclopedia

Analogb> synthesizers can also be viewed as a form of analogb> computer, and their technology was originally based on electronic analogb> computer technology.

computer. The Columbia Encyclopedia, Sixth Edition. 2001-05

Although analogb> computers are commonly found in such forms as speedometers and watt-hour meters, they largely have been made obsolete for general-purpose mathematical computations and data storage by digital computers.
Because of this feature, analogb> computers were especially useful in the simulation and evaluation of dynamic situations, such as the flight of a space capsule or the changing weather patterns over a certain area.
The key component of the analogb> computer is the operational amplifier, and the computer’s capacity is determined by the number of amplifiers it contains (often over 100).
