Amplifier and Filter for Geophone Sensitivity Studies

A geophone is a device that response to the velocity of the ground by the movement of the magnetic mass back and forth to produce a voltage. Generally, geophone can measures a various frequencies of seismic events but there is a limit of frequency that frequencies should be over to get an accurat...
