THE ITERATIVE ALGORITHMS OF A DETERMINATION OF ANALOGUE SIGNALS SAMPLING FREQUENCY IN THE CONTROL AND THE SUPERVISING SYSTEMS
Sampling frequency of low-frequency signals is defined by errors of three processes: sampling; recovery; signal delay. The estimation of influence of these three processes traditionally is based on the use of concept of boundary frequency. At increasing of accuracy of representation of sensors signals there are problems of obtaining of their finite spectrum and determination of a value of boundary frequency. In work the iterative algorithms of a computation of sampling frequency of real signals in control and supervising systems without use of concept of boundary frequency are considered.
