ABSTRACT:
A geophone amplifier including a low cut filter which provides non-linear amplification of the signal to produce a substantially flat frequency response so as to enhance high frequency signals containing high resolution information. Discrete plug-in modules are used to custom design the parameters of the system to increase the signal-to-noise ratio and provide a signal which is conditioned for transmission to a data collection unit. Low power drain circuitry is used so that the system can be implemented as a portable unit for conditioning the seismic geophone signal prior to transmission over a long distance.
