What Is Geophone?

It is then passed through an analog low-cut filter. The data are filtered by the analog high-cut filter so that frequencies above Nyquist are removed and then amplified again. Geophones are remarkably simple devices, unlike what you might think.
The active element of the device consists of a mass hangi...
