AbstractA new method for estimating the self-noise of the measuring channel of a seismometer is proposed, taking into account the linear relationship between the signal and noise. The method extracts noise using records of two identical measuring channels on the example of the SM-3KV short-period seismometer with an operating frequency range of 0.5...

Distribution laws and confidence limits are derived for the relative error of a complex measuring channel that contains several simple measuring channels. Calculations are performed with the assumption that the error of each simple measuring channel has uniform distribution on a specified section. It is shown that divergences of the values of the r...

A virtual instrument has been designed to measure the operating efficiency of hydroelectric equipment. A mathematical model of the dynamic systematic error of a measurement is obtained, which is used to optimize the mode of operation of the instrument. A test bench is developed for checking similar virtual instruments.
