Choice of a window function in the mathematical processing of the measured magnetic field of a flaw in a ferromagnetic product
It is shown that a window function proposed permits to remove random noise from a signal due to its closest adaptation to the magnetic field. The window function is parametric. Varying the parameters, it is possible to change characteristics of the window over a fairly wide interval which overlaps t...

| Zusammenfassung: | It is shown that a window function proposed permits to remove random noise from a signal due to its closest adaptation to the magnetic field. The window function is parametric. Varying the parameters, it is possible to change characteristics of the window over a fairly wide interval which overlaps the domain of variation of known window functions. |
