3 стоту случайного процесса fcj), по формуле /ср ЯрЛТо, где п - сила пересечений коррел ционной функцпп с осью абсцисс, затем вычисл ют/м ,,,, по формуле макс 5 f - bvшкс° 27 7 4л Го-/г,(0)+2ГоЕ/г.г.( ГоСОз2 /ср;То -В качестве /. п /,; принимают значени /,..„ и /макс соответстве.пю и определ ют спектральную плотность процесса в этой полосе. 10 4 Предмет изобретени Способ определени спектральной плотно ти случайного процесса путем измерени его коррел ционной функции, отличающийс тем, что, с целью сокращени времени спектраль °™ анализа, по значени м коррел ционной функции определ ют граничные частоты /м„и и/1ма,1с спектра исследуемого процесса, принимают первую за начальную, а вторую за конечную частоту анализа процесса и в этой полосе частот определ ют спектральную плотность .3, the stochastic process fcj), according to the formula / cf YarLTo, where n is the intersection force of the correlation function with the abscissa axis, then calculated / m ,,,, according to the formula max 5 f (0) + 2ГЕЕ / g. (ГОСОЗ2 / cf; To-As /. P / ,; take the values of /, .. "and / max correspondence. They determine the spectral density of the process in this band. 10 4 The subject of the invention is a method for determining the spectral density of a random process by measuring its correlation function, characterized in that, in order to reduce the time of the spectral analysis, by the values of the cutoff function is determined by the boundary frequencies / m „and and / 1м, 1c of the spectrum of the process under investigation, they take the first as the initial, and the second as the final frequency of the process analysis and in this frequency band the spectral density is determined.
