In this paper, we analyze and optimize the PGC demodulation algorithm for optical interferometers in order to extend its usage in low-cost all digital schemes. In our low-cost system, we choose heterodyne interferometer and direct modulation on Distributed FeedBack (DFB) laser and optimize the algorithm, as well as some of the system parameters in order to have the best linearity and noise performance...
Optimization of interruption performance in high voltage circuit breaker is mainly the optimization of dielectric recovery, among which the nozzle optimization occupies an important position. Because the optimization of dielectric recovery involves numerical calculation of electric field and flow field, time consuming becomes the bottleneck of nozzle optimization. Therefore, a new calculation method...
This paper discussed the different simply approximate calculation methods in applying the model theory to the excitation function approach in calculation of the electrical field of radio interference. If assuming that the electromagnetic field generated by radio interference propagates in the homogeneous medium, the parameter matrix of impedance and admittance will have simply forms and the components...
