A number of advantages may be gained when a digital replacement for an analogue computer is used in a hybrid computing system. This paper describes the interfacing characteristics of the MBD-24 parallel digital simulator and the language which has been developed to control it from a Data General NOVA 820 minicomputer. The language uses the CALL statement of Data General's extended BASIC and the necessary format of these statements is explained. To illus trate the use of the hybrid system and the language, the simulation and measurement of the transfer func tion of the active filter is described.
