EN It is noted that for small sampling periods the superiority of the delta operator (DO) models over the shift operator (SO) concerns only recording of model coefficients and some analytical calculations. It is aslo noted that in the simultations, making it possible to obtain the time response of the output for any input, as well as in the model identification under limited measurement accuracy, the superiority of the DO over SO models, for small sampling periods, disappears. These observations have an essential meaning since the mentioned problems of simulation and identification are important for applications.
