### Rainbow 5.11.5 description

Rainbow 5.11.5 provides you a powerful Spectral Estimation Method for a Power Spectral Density plot. A menu of 10+ spectral estimators from Steve Kays textbook Modern Spectral Estimation 1988 is available to choose from. The results differ dramatically from one estimator to another. Plus, varying input parameters and/or number of points may provide discrepancies.

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.

Major Features:
1. Rainbow (tm) program calculates a Power Spectral Density (PSD) estimate from 1 of several Steve Kay's Estimators. Kay's modern Estimators have shed new light on signal detection. Detecting a signal 50+ dB down is now -very- possible.
2. Rainbow (tm) has a menu of Spectral estimators from Steve Kay's textbook, titled "Modern Spectral Estimation", 1988. The results differ dramatically from one estimator to another. Plus, varying input parameter(s) and/or number of points may show discrepancies.
3. Estimation methods in Rainbow include Autocorrelation, Covariance, Prony, Akaike, Burg, Recursive Maximum Likelihood Estimation, Modified Yule-Walker Equations and others.
4. This picture/plot shows a PSD plot for one of the thirteen methods available to choose from. The methods can vary dramatically in their results. Try several before choosing which estimation is best to represent your PSD.
5. 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.
