Description

Известные способы анализа спектра временных функции основань: на ис110Л1 зовап 1и полосовых фильтров и требуют выполнени  сложных расчетов с болыао затратой времени.The known methods of analyzing the spectrum of temporal functions are based on the use of bandwidth filters and require complex calculations with a lot of time.

Предлагаемы способ определени  епектральноГ нлотности времс ных функций не имеет у уазанных недостатков. Он состоит в следующем: снимают отсчеты анализируемой функции через равные интервалы времени , умножают значени  каждого из отчетов на соответствующие гапмоники спектра и затем суммируют полученные произведени .The proposed method for determining the spectral density of time functions has no drawbacks. It consists in the following: taking samples of the analyzed function at equal intervals of time, multiplying the values of each of the reports by the corresponding spectrum hapmonics and then summarizing the obtained products.

На чертеже изображена блок-схема предлагаемого способа.The drawing shows a block diagram of the proposed method.
