Method and device of determination of a physical parameter represented by the change in the course of time of a physical magnitude.

摘要

The invention relates to a method of determination of a physical parameter represented by the change in the course of time of a physical quantity g, which can vary between a minimum value gm i n and a maximum value gm a x, characterized in that it consists in measuring the physical quantity g, at intervals of time variables, referred to as sampling time, to determine, after each measurement of the physical quantity g, the corresponding value of the physical parameter, as well as the theoretical maximum error induced by the determination of the physical parameter, and to be determined before each new measurement of the physical quantity g, the sampling time, so as not to exceed a predetermined error threshold ts for x during the determination of the value of the physical parameter corresponding to the new measurement of the physical quantity g / p
