  • Abstract
    Given a signal which is available for measurements and consists of the sum of a bias and n sinusoids with unknown amplitudes, frequencies and phases, a dynamic algorithm is designed to recover online the unknown values of the frequencies, for any initial condition and any value of frequencies, amplitudes and phases.
