A quantitative trial on compound and cumulative effects in measurement of illumination - electromagnetic environment under quantized level observation

摘要

A quantitative evaluation method on compound and cumulative effects of illumination - electromagnetic environment is developed by considering various types of their higher order non-linear correlation. A regression analysis method considering not only a linear correlation hut also the higher order nonlinear correlation information is proposed in a form suitable for signal processing by using a digital computer and digitized observation, especially in order to find minutely the mutual relationship among light and electromagnetic waves leaked from electronic information equipment. An extended type regression analysis method hierarchically reflecting various types of correlation information is theoretically derived by introducing an expression on the multi-dimensional probability distribution in an orthogonal expansion series form with discrete level type. Finally, the proposed method has been experimentally applied too to an evaluation problem of electromagnetic field and illumination leaked from VDT of television games through their quantized level observations and their mutual relationship.
