Abstract
A physical interpretation has been given to the clustering Poisson process
which results in a 1/f spectrum; this model is compared with a model in
which the 1/f spectrum is derived from a superposition of the Lorentzian
spectra. For a point process, an expression has also been derived for the
high-frequency limit to 1/f fluctuations buried in shot noise.
