NOISE INFLUENCE ON THE MULTIPLE MEASURING METHOD

T. Wada, T. Ono

Abstract

The multiple measuring method, that is, the double measuring method or its improved version, provides a precise calibration procedure of linear sensors as well as a linear system identification method, whose results are independent of dynamics of measuring devices. These methods are established on the assumption that measurement noise can be ignored. In practice, however, measurement noise exists and it cannot be ignored. In this paper, the influence of measurement noise is investigated on the result obtained by applying the multiple measuring method. Consequently, the influence is appeared as the signal-to-noise ratio at an observed output and it is removed by the principle of the multiple measuring method.
