Abstract:
It is indicated that the known methods for measuring some initial signal lead to errors if the width of the measuring intervals does not step by step adapt to changing signal parameters. A new approach to measurement is used, revealing a unified physical basis for measurement and instrumental computation. A new algorithm as a consequence of this approach is designed to obtain a sequence of discrete samples that matched to locally determined averaging intervals. Resulting sequence of averaging intervals ensures a decrease in the measurement or computing error. The results of calculations on three arrays of samples are presented with fixed and adaptable averaging intervals.
Keywords:
averaging interval, measurement uncertainty, patent.
