Find best Spectral Estimation Method for a Power Spectral Density plot. A menu of 10+ spectral estimators from
Steve Kay"s textbook, Modern Spectral Estimation, 1988, is available to choose from. The results differ
dramatically from one estimator to another. Plus, varying input parameter and/or number of points may provide
See how zero padding effects your results. Manufacturing companies take note! Some estimators can detect
signals 50 to 100 dB from main signal. See documented example! The unwritten rule of '30 dB is okay' (i.e. hidden)
is no longer true.
