Energy Spectral Density and its Implementation in Matlab
Introduction:
ESD shows energy distribution in frequency spectrum. Its units are jouls/hz. Total Energy of signal is area under ESD of signal. This relation is provided by Parseval’s Theorem, which relates energy in time domain to the energy in frequency domain.
That is:
Where |X(f)|2 is Read the rest of this entry »
