METHOD FOR DETERMINING THE COORDINATES OF THE POINTS OF INTERSECTION AND TRANSITION OF THE ABSCISSA AXIS WITH THE TRAJECTORY OF A SINGLE-VARIABLE FUNCTION AND SOME FEATURES OF ITS APPLICATION

Abstract

This article presents a new technique using a conditional electrical signal. The presented method not only solves the problem of identifying specific moments (ti) at which the signal trajectory crosses the time axis, but also allows you to accurately register cases when the signal trajectory comes into contact with this axis. It is assumed that the problem under consideration is solved by using appropriate mathematical tools. This choice is justified by the extensive use of digital signal processing methods in modern measuring instruments, relay protection systems and emergency automation systems, especially in power systems.
