Analysis data from Accelerometers to get 1/3 Octave center frequency, natural frequency and RMS Acceleration of floor

Post by HungPhung » Thu Oct 11, 2018 12:43 pm

Dear all,
(first, forgive me for a beginner question)

I am doing a small project which I was given an Accelerometers (Model: 393A03 from pcb.com) and I need to get the 1/3 Octave center frequency, natural frequency and RMS Acceleration of floor (or some hard surface).

I have the Accelerometers working and connected to PC using the PicoScope software and get the data; it is in mV and time format.

Could I ask if there is any code in Mathlab to analysis the data to get the frequency, 1/3 Octave center frequency, natural frequency and RMS Acceleration?

In the Pico software, I take the data when the action (drop a heavy object) and also the raw screen shoot of the Pico. I cant upload the data due to size. I have it here: https://goo.gl/bSy3B1

Hi HungPhung,

We don't have any examples of performing this sort of analysis and it may require functions from a MATLAB toolbox. You may wish to look at the following Toolbox information pages to see if there might be something that helps:

Audio System Toolbox:

Signal Processing Toolbox:
