period for data window df = 1/T; frequency resolution nfft = T * fs; number of points in fft Load acceleration data fn = input('Name of data file?','s');

The choice of code for Fast Fourier Transformation of acceleration data in the time domain is limited to a Matlab code, since it is a valid and available code
