NEW METHOD OF SUMMATION FOR MEASUREMENT ERRORS BASED ON PIECE-WISE LINEAR APPROXIMATION OF PROBABILITY DISTRIBUTION

Sergey Y. Yurish et al

   The article describes a new method for summation of measurement errors. It is based on the piece-wise linear approximation of probability distribution (frequency function). The calculation results are compared with the calculation according to the well known technique and example. The offered method allows to increase the accuracy of determination of the numerical characteristics for resulting error up to 10-11 % and to visualise the resulting distribution low. A software package for IBM PC compatible computers is realised.

Keywords: measurement, probability distribution (frequency function), characteristic function, measuring error, virtual instrument
