A Study of the Applications of Analog Computers

An electronic analog computer is a tool for solving mathematical differential equations. The basis for the use of such a computer in the simulation of many scientific and engineering problems is the possibility of characterizing these situations as formal mathematical systems by using differential equations. In this paper, following a brief description of the computing elements, the applications of analog computers in the study of various linear, nonlinear, and time-varying systems are described with typical illustrative examples from diverse fields of interest. Computer applications in solving partial differential equations are also discussed. Potential capabilities and limitations of this type of computer as an aid in research and analysis are given.
