| Abstract: | Through analyzing a new full voltage, single crystal, longitudinal-mode Pockels-modulator electro-optic voltage transformer's inner principle and aiming at the error caused by the nonlinearity, a nonlinear subsection interpolation arithmetic is put forward. The capability of two arithmetics of nonlinear subsection interpolation and linear subsection interpolation is compared and analyzed, finally,through digit simulation, the theory analysis is confirmed, the gist is provided for the choice of voltage signal resumption. |
