WebSo to achieve a gain of 5V/V, you will need to select an Rf value that is 4X the Rg value. So if you modify the 3.3M resistor to 26.8k the equation solves for 5V/V. Gain = 1 + (26800 / 6700) = 5V/V. Regards, Collin Wells. Anonymous over 11 years ago in reply to Collin Wells. Guru 17045 points. WebA geophone is a device that converts ground movement (velocity) into voltage, which may be recorded at a recording station. The deviation of this measured voltage from the base …
WebThe calibrated geophone is computed with a constant factor equal to the ratio of the amplitudes of the hydrophone and geophone. We calculate a constant factor per trace, we average all of them, and nally apply the averaged constant factor to the entire shot gather. This procedure not only calibrates the geophone but also eliminates the ghost ... WebA geophone is a ground motion transducer that has been used by geophysicists and seismologists to convert ground movement into voltage. Any deviation in this measured voltage from the base line is regarded as seismic response, which is used for analyzing the earth’s structure. Resonance frequency is the key factor in a geophone, and it has to ...

WebNov 11, 2016 · The impedance of the geophone is low at 630 ohms so bipolar transistor input operational amplifiers can be used for lowest noise which explains the selection of the LT1677. The rail-to-rail inputs and outputs of the LT1677 allow 3 volt operation but a higher voltage design could use something like an LT1007, OP-27, or maybe LT1028/LT1128.
