Since m0 is the total variance integrated over all frequencies, the standard deviation is given by σ = √m0 (see Eqs. 3.4.3.3 and 3.4.3.4 ). In Sect. 3.4.4 we will see how the zero-th moment m0 and the second moment can be used to determine the zero-crossing period from the spectrum.SPECTRAL ANALYSIS.
