Sine wave parameter estimation method

摘要

Vis-a-vis the unknown signal, the input signal is measured. And from the value, the technology which presumes the parameter (frequency, amplitude and phase) of the sine wave which is included directly in that input signal is offered. It raises the governing equation of the analytical signal, it replaces to integral calculus type furthermore by introducing optional load function. Sine wave parameter is presumed by solving that. As a result, it was not the presumption with former approximation, compared to it reached the point where it can obtain the parameter of the sine wave strictly.
