Mechanical vibration and shock -- Signal processing -- Part 2: Time domain windows for Fourier Transform analysis
This standard was last reviewed and confirmed in 2013. Therefore this version remains current.
ISO 18431-2:2004 specifies the algebraic functions which describe a selected set of time domain windows used for pre-processing digitally sampled vibration and shock data as a precursor to Discrete Fourier Transform spectral analysis. This selected set consists of Hanning, flat-top and rectangular time windows.
