Confidence Bounds of the Error of a Complex Measurement Channel of a Measuring System

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. I...

Zusammenfassung:	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 relative errors calculated for the composite error distribution of the complex measuring channel and for the normal distribution with the same value of dispersion do not exceed 3%, with a confidence probability of P = 0.95.
