Abstract
The paper outlinies the direct-analog approach used on the Anacom and describes the sigma amplifier which combines adding, integrating, delay, and other operations into a single computer amplifier and results in an improved computing technique. Examples include a speed-regulating system, and systems of simultaneous differential equations such as the aerodynamic equations of flight of an airplane. An adjustable nonlinear resistor and other functional devices are described, together with their use in analogs of fluid flow, saturating iron cores, magnetic amplifiers, and hysteresis. An analog for corona is given.Keywords
