Seismometer Amplifier
Amplifier circuit.
The amplifier above consists of two 741 op-amps in a "follower-with-gain" arrangement.
Capacitors on the input function to suppress high frequency signals which may
represent a large component of the site-specific seismic background
"noise." Use the lowest value capacitors that will suffice for
your equipment and your location. This is probably a
"trial-and-error" approach.
