Analog Computer

Analog Computer
  • It is the type of computer that represents data in terms of physical measures or quantities and proceeds along a continuum constituted by its components. Analog computers are especially suited for the solution of complex non-linear equations and for the simulation of multi-dimensional, parallel and continuous processes.
  • There is no restriction on the physical processes analog computers may utilize. In general, analog computers are extraordinarily fast, since they can solve most complex equations at the rate at which a signal traverses the circuit, which is generally an appreciable fraction of the speed of light.
  • On the other hand, the precision of analog computers is not good; they are limited to three, or at most, four digits of precision. Compared with digital computers, the programming of analog computers is time consuming and limited in scope.
