ABSTRACT:
To test a seismic sensor, an output of the seismic sensor in response to a test signal applied by a signal generator is measured. According to a first function that corresponds to a reference response of the seismic sensor and according to a second function that corresponds to a signal containing noise in an environment of the seismic sensor, a filter is created to perform attenuation of the noise. The filter is applied to attenuate noise during testing of the seismic sensor.
