We got the results of the wiener filtering simulations (Elog Entry)
We got the power spectra and coherence of the seismic noise measurements from GURALPs and STS seismometers (Elog Entry)
We tried to whiten the target and the input signal for the computation of the wiener filter for the real data, but the results are unsatisfactory. We should not care about high frequencies in wiener filter computation so we will just filter them off in the filter output with a low pass filter.
We just found the right gain for the system seismometer-AAboard-ADC (Elog Entry)
