extraction of complex frequencies and amplitudes from time series


Harminv is a free program to solve the problem of harmonic inversion, given a discrete-time, finite-length signal that consists of a sum of finitely-many sinusoids (possibly exponentially decaying) in a given bandwidth, it determines the frequencies, decay constants, amplitudes, and phases of those sinusoids.
