This pocket book is a modern treatise on "Analog Computer Programming". It is intended to give a thorough introduction into this area. It covers the basic computing elements, Kelvin's feedback technique, time and value scaling etc. In addition to this it contains a wealth of practical programming examples ranging from simple problems such as radioactive decay to quite complex simulations like airflow over an airfoil, chaotic systems, ballistic trajectories and many more. Due to its low price and handy size it is an ideal vade mecum for everyone interested in analog computing.



This modern book on "Analog Computing" gives a thorough account of the historic development of analog computing as well as their past and present applications, programming and much more. It is a treasure trove for all interested in this computing paradigm. (English)



Das Buch "Analogrechner: Wunderwerke der Technik - Grundlagen, Geschichte und Anwendung" behandelt neben der historischen Entwicklung der analogen Rechentechnik typische klassische und moderne Anwendungsbereiche derartiger Rechner. Darüberhinaus enthält es neben einer Einführung in die Programmierung elektronischer Analogrechner eine Reihe praktisch ausgeführter Programmierbeispiele und vieles mehr. Inhaltlich entspricht es dem oben verlinkten Werk "Analog Computing".

Application Notes

The following section contains links to analog computer application notes (humorously known as "alpacas" in-house) which describe practical applications of analog computers such as the implementation of chaotic attractors etc. This section will get extended at irregular intervals so check from time to time for new publications.


This is the first article in the series "Analog Computer Applications" by Analog Paradigm. This issue covers the so-called Rössler-attractor and its implementation on an analog computer in detail. Happy analog computing!


This second issue of "Analog Computer Applications" deals with the well-known Lorenz attractor. Happy analog computing!


This third issue of "Analog Computer Applications" describes the basics and implementation of a so-called Chua-oscillator.


The fourth issue of "Analog Computer Applications" deals with conformal mappings and the simulation of airflow around cylinders and Joukowsky airfoils.


The fifth issue of "Analog Computer Applications" describes a high-speed simulation of a bouncing ball.


"Zombie Apocalypse Now" - simulate a world infested by zombies with an analog computer.
