We use the response waveform from the calibrating with step or steady sinecurrent to calculate the transfer function of a seismometer.
介绍了利用地震计对阶跃电流标定或稳态正弦电流标定的响应波形获取地震计传递函数的方法。

Simulation and experimental results show that the proposed converter has sine wave input current and output voltage, low harmonic content, adjustable power factor, and zero voltage commutation.
It's discussed that the method of RMS and frequency measurements directly from the wavelet transform data associated with each sampling sine voltage (current) element pair containing harmonic.
