Example 1:
Data examples from a shear wave vibro survey in a 100 m borehole.
Sampling rate 1 ms, sweep length 10 s, 20 to 150 Hz
Three traces are X, Y, and Z-Component.
Example 2:
Data example from correlated shear wave sweeps under severe powerline noise surrounding. Sampling rate 1 ms, sweep length 20 s.
Left trace P-Wave, right trace S-Wave
Complete absence of powerline noise 50 Hz, 150 Hz, 16.66 Hz.
