An accelerometer was used to measure the vibrations of machinery. The sensor output was acquired during an experiment for 20 s at a rate of 2048 Hz and spectral analysis was performed using FFT. 1) What is the range of frequencies where the power spectrum can be evaluated 2) What is the frequency resolution for the power spectrum plot 3) Will any zero padding needed for this data set when using the FFT algorithm? 4) Do you recommend data windowing? Why? 5) If the data set was split into 5 sets (4 s long each), what is the effect of performing this process on the frequency range, frequency resolution, and the variance of the spectral estimate?
