WIPO Patent Application WO/2007/108492
Kind Code:
A1
Abstract:
Provided is a probability density function isolating device for isolating a
predetermined component from a given probability density function. The probability
density function isolating device includes: a region conversion unit for receiving
a probability density function and converting the probability density function
into a frequency region spectrum; and a standard deviation calculation unit
for calculating a standard deviation of a random component contained in the probability
density function according to the spectrum.
