====Blades====

For analysis of torque on a single blade, the spikes occur at <math>k'\Omega_0</math> where ''k''' is 1,2,3,..<ref>Aerodynamics of Wind Turbines, Martin O. L. Hansen</ref> This can be seen from taking the autocovariance of equation 1, and then taking the Fourier transform of this result.

==Stochastic processes ==

Stochastic processes are those belonging to turbulence. These require a purely probabilistic approach. A stochastic process such as turbulence is stationary. Analysis of stochastic processes reveals that they present themselves as broad peaks on a power spectrum.
