| Abstract: | The tester for supergeophone is a tool for accurately measuring, it should have the power of antinoise. To acquire a precise and reliable result in measurement, besides the instrument itself has sufficient accuracy and reliablity, data processing and result analysis can not be neglected as experiment design. The way to develop a tester for supergeophone is pointed out.One must strengthen the power of antinoise based on increasing the bits of A/D converter appropriately, that is, one must take measures as filtering or other technique to depart noise from the signal. A geophone response signal added by a Gaussial white noise is connected to a 16 bits A/D converter model, with Marquardt method to identify geophone's natural frequency and damping.This method is expected to be used in supergeophone tester for improving the accuracy. |
