METHOD AND APPARATUS FOR VARIANCE ESTIMATION IN AMPLITUDE PROBABILITY DISTRIBUTION MODEL

摘要

A variance estimation apparatus for an amplitude probability distribution (APD) model includes: an APD curve calculation unit for calculating an APD curve of an APD model for noise of an electronic device; and a linearity determination unit for determining a linearity of a slope of the APD curve calculated by the APD curve calculation unit. The apparatus further includes a variance processing unit for selectively performing equivalent variance processing or different variance processing based on the linearity determination result obtained from the linearity determination unit.
