OLCA: An on-line circuit analysis system

An experimental software system for on-line analysis of linear networks is described. Inputs to the system such as circuit diagrams are given via the light pen and the teletypewriter of a remote graphical console. Analysis results are available in various forms, including console displays of frequency characteristics. The system provides close user supervision so that it is easy to use even for a network designer without direct computing experience. Some typical operations at the console are described. The interaction strategy employed and the data structure used are also presented.
