I wrote the question in so strange sentence, that I don´t even understand it myself :). What I wanted to ask from Greglocock is:
Range F12 - there should be inside equation instead of $A$4 a $B$4 range?
I have a PSD chart from the same data. The g-vlaues are not RMS-ed.
This data post-processing field is too unknown for me :). I should do my homework properly. I´ll just start seeking handbooks and articles. Then I´ll get back to you if I am still in trouble.
Greglock, thanks for the...
No there is no frequency dependance. I am trying to extract basicly the area under acceleration curve (the work, which the acceleration does). And then line it up to see which average acceleration values are most useable (which occur most often and last the longest).
I am not trying to find average or max values of acceleration. I am trying to create a 3D plot with following axes:
x - intervals of acceleration duration in seconds
y - average value of acceleration in these intervals
z - probability density of these intervals or the count how often did the...
The data is in following format:
-0.0367906
-0.00433198
-0.00831627

There is 1025243 lines in this file. Its the resuts of accelerometer from automotive vibrations. Measured with sampling rate 512Hz.
I would like to get a chart which describes which acceleration levels have the longest...
To be honest, i dont remember much about Fourier analysis from school time. Only thing I can remember is that it allows to replace an orginal function with bunch of sine or cosine functions. So I looked into some digital signal procesing handbooks and the first thing i noticed was the time...
Hi,
I would like to extract out of acceleration measuring data a chart, which consists acceleration value, its existance length in seconds and the occuring frequency. I think it is called interval average acceleration versus time chart.
The acceleration data is basicly noise filtered values...
