METHOD FOR IDENTIFYING MULTISINUSOIDAL DIGITAL SIGNALS Russian patent published in 2023 - IPC G01R23/16 

FIELD: multisinusoidal digital signals identifying.

SUBSTANCE: present invention sets the task of identifying a multisinusoidal digital signal, which allows filtering the signal using a structural converter, counting the number of harmonic components of the signal in the identifier of a continued C-fraction, evaluating the signal parameters (amplitude, frequency) in stages as their amplitude values decrease in the restorer harmonic model with subsequent restoration of the signal residual, determine the presence of an offset and restore its value, thereby expanding the scope of the identification method for various types of multisinusoidal signals, automatically determining the structure and parameters of the useful signal.

EFFECT: increasing the accuracy, reliability and speed of the identification process, which makes it possible to use this method as a method for current identification in real time, to determine the change in the structure of the model and thereby improve the accuracy, reliability and quality of the results.
