Abstract
The power spectrum G(f) of a random process cannot be determined exactly, because measurements can be made only for finite intervals of length T. Therefore, the calculated power spectrum is only an estimate (represented by \( \bar{G}\left( f \right) \) or \( \bar{P}\left( f \right) \) ) and is not identical with the true power spectrum.
