METHOD FOR STEP-BY-STEP ADAPTATION OF THE WIDTH OF MEASUREMENT INTERVAL TO SIGNAL PARAMETERS [PDF]

open access: yesVestnik KRAUNC: Fiziko-Matematičeskie Nauki, 2019
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
