Demonstrationsbeispiele fur Analogrechner RAT 740 — Beispiel 2: Einfache Darstellung einer Planetenbahn
A short German-language application note (3 pages, dated 1 November 1966) from Telefunken's Analog Computer Department, presenting Example 2 in a series of demonstration programs for the RAT 740 analog computer. The document describes a simplified simulation of planetary orbital motion using Kepler's laws: an elliptical orbit is generated via sine-cosine function generators and multipliers, with the orbital eccentricity and semi-axis adjustable via potentiometers, and the result displayed on an oscilloscope as a Lissajous figure. Page 3 contains the full patching/wiring diagram for the RAT 740 implementing this circuit.
