Web5. Power spectral density (PSD) function: The PSD function is one of the most comprehensive statistical methods for measuring surface roughness. It allows for a complete description of the surface texture characteristics by providing the relative strength of each roughness component as a function of spatial frequency. WebA PSD is computed by multiplying each frequency bin in an FFT by its complex conjugate which results in the real only spectrum of amplitude in g 2.
