Пусть такое колебание x( t) задано

Пусть такое колебание x( t) задано в виде некоторой функции, отличной от нуля в промежутке ( t 1 , t2 ) (рис. 2.1). Выделив произвольный отрезок времени T, включающий в себя промежуток ( t 1 , t2 ) , можно пред-ставить заданное колебание в виде ряда Фурье

Let this fluctuation of x (t) is specified as a function different from zero in the interval (t 1, t2) (fig. 2.1). Selecting an arbitrary length of time T, which includes period (t 1, t2), you can submit the specified oscillation in the form of a Fourier series
