Позорная война рф против Украины

Начата 20 февраля 2014 и полномасштабно продолжена 24 февраля 2022 года. С первых же минут рф ведет ее с нарушением законов и правил войны, захватывает атомные станции, уничтожает бомбардировками мирное население и объекты критической инфраструктуры. Правители и армия рф - военные преступники. Все, кто платит им налоги или оказывают какую-либо поддержку - пособники терроризма. Народ Украины вас никогда не простит и ничего не забудет.

A method for processing the signals of eddy current flaw detection is proposed. It is based on determination of the number of zeros of the analyzed signal in the sliding mode. The method features low resources capability, has simple circuit implementation and can be used in automated systems of eddy current nondestructive testing. 13 Ref., 1 Tabl., 4 Fig.
