Abstract:
There is provided a noise separating apparatus that separates a probability density function of a predetermined noise component from a probability density function of a signal under test. The noise separating apparatus includes a domain transforming section that is supplied with the probability density function of the signal under test and transforms the probability density function into a spectrum in a predetermined variable axis, and a standard deviation computing section that computes standard deviation of a random component of noise contained in the signal under test based on a magnitude of a predetermined variable component in a main lobe of the spectrum.
