Paper Abstract
Previously we derived the probability density function (PDF) of the zero-crossing interval for 1/fα noise and found that the PDF, L(t) obeys the power law of the form 1/tc whose exponent c relates to
the exponent α of the power spectrum density as c = 3-α when 0 < α < 1 and c = (5 - α)/2 when 1< α < 2. (Proc. SPIE Vol. 5471, p. 29, 2004).
This analytical result agreed with numerical experiments by Mingesz et al. (Proc. SPIE Vol. 5110, p.312, 2003) for 0.7 less than or equivalent to α < 2,
but not for 0 < α less than or equivalent to 0.7;
the experimental PDF deviates from the power law in the latter range.
We present here a discretized version of the previous theory by noting
that the experimental time interval takes discrete numbers.
The present result agrees well with the experiment for
the whole range of α and explains the deviation from the power law of
PDF in the range of small α.
