Additions to z-transformation theory for sampled-data systems
V. Gladwyn Lago · Transactions of the American Institute of Electrical Engineers Part II Applications and Industry · 1955
THERE is one important class of feedback control systems which until recently has received but limited attention. The systems in this class are known as sampled-data systems. The distinguishing feature of this class of systems is that at one or more points in the system, signal information has the form of a train of pulses.
