In this paper we consider a method for determining the quantization frequency of the zero-order extrapolator in the frame of the digital position-tracking system. The analysis is carried out by the frequency approach. Amplitude frequency specifications of discrete systems are defined as the sum of the shifted amplitude-frequency characteristics of the analog part of the system. In this connection, it is necessary to determine the shifting frequency of the amplitude frequency characteristics of the system’s continuous part so that their sum in the frequency band of the reference signal does not exceed the specified error regarding the analog prototype. The obtained value of the quantization frequency of the extrapolator will determine the interval of discreteness.
