Abstract
Frequency characteristics of the procedure of spline-smoothing of information coming in real time are obtained. A recurrent spline is studied from the standpoint of the theory of linear dynamical systems. The estimation of quality and sustainability of the recursive spline filter are described. The spline transformation laws identified in a frequency analysis are confirmed by the indicators of smoothing quality in the time domain.
