HVSR frequency band

Post by laleh »

Hello,

I run HVSR on data and filter it for example up to 25 Hz (under the time windows tab). Then I set frequency sampling to 0.5-125 Hz under the output tab. in the HVSR plot, I can still see peaks around 100 Hz, despite filtering signals up to 25 Hz. I am wondering what is the reason for that? does the HVSR plot show the results from the filtered signal or the raw one? (please see the figure attached)

Thanks,
Laleh
