The mathematic models of dielectric loss including the adding noise and modulating noise are proposed.The problems existing in the on-line measurement are briefly presented, and the technical scheme based on the optimization filter theory, which is realized by digital-analog multiplication technology is proposed against these problem, and further more the error of it is analyzed in detail. The optimization correlation filter is testified and proved to be the best way to restrain the adding noise and high harmonic. Finally, the result of experiments are given.
