In mathematics and signal processing, the Hilbert transform is a specific singular integral that takes a function, u(t) of a real variable and produces another function of a real variable H(u)(t). The Hilbert transform is given by the Cauchy principal value of the convolution with the function (see § Definition). The Hilbert transform has a particularly simple representation in the frequency domain: It imparts a phase shift of ±90° (π⁄2 radians) to every frequency component of a function, the si… WebDec 12, 2015 · The function is periodic, so a single period of the function can be transformed, and then the transforms of all periods summed. It is convenient to begin by subtracting the average value of the function over the period, which is 2/Pi. Integrate [ (Cos [ω/100] - 2/Pi), {ω, -50 Pi, 50 Pi}] (* 0 *) grassland science 影响因子
