THE ERROR OF GENERATOR FREQUENCIES ESTIMATION IN NONSTATIONARY CASE IN USING OF STATISTICAL STABILIZATION METHOD
179 KB
The article is devoting to further development of the method of statistical stabilization of the generator frequency. The problems associated with the analysis of errors that arise due to non-stationary frequency generators on the interval estimation of frequencies, by using this method. The first component of the error associated with the deviation of the measured phase of the oscillator frequency instability due to its own generator, and the second is determined by the change in frequency of the generator to the range of measurements. It is noted that the reduction of each of the components presents conflicting requirements for the length of the time interval. Based on the known relationships that define the potentially achievable value of the standard deviation of frequency from the nominal value, the expressions that determine the optimal length of the time interval of measuring. The minimum amount of two errors is considered as a criterion in choosing the duration of the time interval. The basic relations that determine the amount of data errors are presented, and the results of numerical simulations are described.
