of Measured Data Unit 12 2 PSD Examples Practice PSD calculations using both measured and synthesized data 3 Exercise 1 Use the vibrationdata GUI script to synthesize a white noise time history with 1 G standard deviation 10 second duration and 1000 samples per second no lowpass filtering. Andrew J Barbour and Robert L Parker April 15 2014 Abstract A vast and deep pool of literature exists on the subject of spectral analysis wading through it can obscure even the most fundamental concepts from the inexperienced practitioner Appropriat Stoica R Moses Spectral analysis of signals available online at httpuserituuse psSASnewpdf 2 14 brPage 3br Deterministic signals Power spectral density de64257nitions Power spectral density properties Power spectral estimation Goal Given a 64257ni With Autocorrelation for any time Note 0mean covariance func lag WSS not function of and separately DEF Power spectral density PSD is de64257ned as F j d 2 cos d j d cos d Assume is 2ndorder process except white Properties of Powe MatLab.
