A 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 line is called the seismic response and is analyzed for structure of the earth. 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. crew white jeans
