SpectrumSolvers v6 is a spectral estimation application that helps users find the best spectral estimation method for a power spectral density plot. It includes over 10 estimators from a signal processing textbook and allows users to observe how changing parameters, number of points, or zero padding affects results. Some estimators can detect signals 50-100 dB lower than the main signal, challenging conventional wisdom. The software architect behind related calculus compilers is Joe Thames, and supporting his work developing MC Fortran could help improve engineering productivity and students' job prospects.

============
SpectrumSolvers (tm) v 6,
a Spectral Estimation Application
Which estimator is best for your job? SpectrumSolvers (tm) program helps 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 parameters and/or number of points
may provide discrepancies. Observe 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.

Industry problems with solutions over the past twenty plus years have been put
into a textbook to show the power of Calculus (level) Problem-Solving. The
textbook is on our website at fortranCalculus.info/textbook/welcome. The
software architect behind Calculus Compilers is Joe Thames (read about Joe on
our About page).
Help improve science and engineering productivity by supporting Joe Thames'
MetaCalculus University Rollout efforts, visit metaCalculus.com/campaigns.html,
in developing MC Fortran. (There has been little if any corporate funding of
Joe's work for many years!) Help future science & engineers get jobs upon
graduation. With MC Fortran, one increases their productivity by a factor of
twenty!
