Doubt with filter

Post by llem0 »

Dear Seismosoft team:

I am testing two accelerometer with a frequency of 1 Hz . How do i know what bandpass filter to use?. I am working between 0.1 Hz to 25 Hz.

Kind regards!

Hi llem0. I am not sure I fully understand your question. Are you working with accelerograms recorded on a particular device? It seems that the science of properly selecting bandpass ranges for given records may be outside the scope of the forum. It can be very difficult to zero in on the range which will produce an accurate displacement history. Fortunately, the acceleration response spectrum often doesn't alter drastically post-filtering over a significant frequency range. So, depending on what you are interested in, you may want to refer to the literature on methods used to establish bandpass ranges to properly process raw ground motion recordings. Best of luck llem0.
