AN ANALYSIS OF THE ERRORS IN CHECKING THE WORKING STANDARDS OF FREQUENCY DEVIATION BY INDIRECT MEASUREMENTS

摘要

In view of the fact that a State Standard of the unit of frequency deviation does not exist in the Russian Federtion, an investigation of the possibility of checking the working standards - the K2-38 equipment - by indirect measurements is an urgent matter. In this paper we given a analysis of the errors of the method of indirect measurements for determining the values of frequency deviation provided by the K2-38 equipment. Consider the model of the K2-38 equipment shown in the figure. It consists of a voltage-frequency converter, at the output of which the instantaneous frequency depends on the instantaneous value of the modulating input voltage. The converter is described by the formula.
