how to calculate FFT and spectrum of acceleration sensor (x,y,z) in python -


i acceleration data (x,y,z) captured smartphone. , want calculate fft , spectrum using python. so, can me how this?

thank you

the following code:

import numpy np import matplotlib.pyplot plt scipy.fftpack import fft, ifft, fftfreq

load acceleration data

df = np.loadtxt('acceldata1.dat')

this case i'm using y axis

n=len(data) y = data[0:n,1:2]

using fftfreq calculate fft

req=fftfreq(n)

in experiment, want calculate fft, spectrum , filter technique, i'm confusing how start fft using acceleration data (x,y,z) because i'm new in signal processing.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
