An analog computer or analogue computer is a type of computation machine (computer) that uses physical phenomena such as electrical, mechanical, or hydraulic quantities behaving according to the mathematical principles in question (analog signals) to model the problem being solved.
The general purpose analog computer (GPAC) is a mathematical model of analog computers first introduced in 1941 by Claude Shannon. [1] This model consists of circuits where several basic units are interconnected in order to compute some function. The GPAC can be implemented in practice through the use of mechanical devices or analog electronics.

Phillips Machine in the Science Museum, London. The Phillips Machine, also known as the MONIAC (Monetary National Income Analogue Computer), Phillips Hydraulic Computer and the Financephalograph, is an analogue computer which uses fluidic logic to model the workings of an economy.
An analog computer is a form of computer that uses electrical, mechanical, or hydraulic phenomena to model the problem being solved. More generally an analog computer uses one kind of physical quantity to represent the behavior of another physical system, or mathematical function. Modeling a real physical system in a computer is called simulation.
The SEA primarily produced computers in small quantities, about a couple hundreds, and occasionally as one-of-a-kind units, most notably for military clients. Six major categories of computers stand out: The CAB 2022 computer installed at MATRA, 1955. Analog computers, from the OME and NADAC family; Unique military models, such as the CUBA and ...
As an analog computer does not use discrete values, but rather continuous values, processes cannot be reliably repeated with exact equivalence, as they can with Turing machines. [58] The first modern analog computer was a tide-predicting machine, invented by Sir William Thomson, later Lord Kelvin, in 1872. It used a system of pulleys and wires ...
Analog Dialogue is a forum for the exchange of circuits, systems, and software for real-world signal processing and is the technical magazine published by Analog Devices. [88] It discusses products, applications, technology, and techniques for analog, digital, and mixed-signal processing. Analog Dialogue is published monthly on the Web. The ...
