Design of an accurate simulator for sampled-data systems
M.J. Somerville, G.F. Turnbell · Proceedings of the IEE Part B Electronic and Communication Engineering · 1962
A detailed consideration is given of certain specialized units by means of which an analogue machine, normally used for simulation of continuous systems, may be adapted to allow also simulation of sampled-data systems. Emphasis is mainly on those circuits and methods which achieve best accuracy, the order of 0.1% being possible when valve circuits are employed.
