ЗАСОБИ ТА МЕТОДИКА ДОСЛІДЖЕННЯ ШУМОВИХ СИГНАЛІВ
Journal Title: Вимірювальна техніка та метрологія - Year 2007, Vol 1, Issue 68
Abstract
The measuring setting on the basis of correlation method of noise tension measuring, intended for conducting of researches of influence structural defects, composition and material’s state of sensible element, mechanical tensions in a primary transformer on a level and spectral composition of useful signal of noise thermometer is considered. The method of filtration of noise signals on the basis of the fast Fourier’s transformation is offered.
