Advanced Mechatronics - Frequency Analysis
Question#01: Describe the procedure of determining the correct sampling rate based on spectral analysis.
Question#02: What is the assumption used to
apply harmonic analysis to functions (e.g.
sets of measured data) for which the period T is not known or for
which the periodicity
itself is questionable?
Question#03: Assume that the vibration data are
measured over 2 minutes. The Fourier
analysis is used to determine the frequency spectrum. What is the
fundamental frequency
as determined from the discrete Fourier transform algorithm?
Question#04: Explain what is the cut-off frequency of a filter.
