Hybrid Techniques for Analog Function Generation
Walter E. Chapelle · afips · 1899
In computing systems involving real-time simulation, data processing, or control, it is often possible to combine digital and analog computing techniques to improve the over-all system capability or performance. Effective combinations of analog and digital techniques have been made at several levels. At the systems level, general-purpose digital and analog machines have been linked through conversion equipment, enabling more effective solution of classes of problems which involve both precision arithmetic operations and rapid solution of differential equations. At the component level the capabilities of digital equipment for information storage, logical decisions, and sequence generation can be used in a variety of ways to augment the capabilities of analog equipment for wideband computation. Finally, at the information representation level, hybrid codes have been utilized to represent variables to obtain high-accuracy computing structures from an assembly of less accurate components.
