Une nouvelle technique de calcul analogique — Le calculateur électronique
A French-language article by CSF describing their AC-based analog computation technique, in which voltages represent variables and cylindrical variable capacitors with servo motors replace conventional DC potentiometers. The article explains the three fundamental algebraic operations (multiplication by a constant, addition, and function evaluation), illustrates example calculator setups for coordinate transformation, differentiation, and integration, and concludes with an extended application to anti-aircraft (DCA) fire-control, showing how CSF analog computers track aircraft, compute firing solutions, and drive gun-laying systems.
