In this study, a signal processing method considering not only linear correlation but also the higher order nonlinear correlation information is proposed on the basis of fuzzy observation data, in order to find the mutual relationship between sound and electromagnetic waves leaked from an electronic information equipment. More specifically, by applying the well-known fuzzy probability to an expression on the multi-dimensional probability distribution in an orthogonal expansion series from reflecting hierarchically various type correlation information, a method to estimate precisely the correlation information between each variable from the conditional moment statistics of fuzzy variables is proposed as a trail. The effectiveness of the proposed theory is experimentally confirmed by applying it to the observation data leaked from VDT periphery in the actual work environment.
