Аннотация
We investigate a nonlinear parametric method of estimating the instantaneous frequency and amplitude of a quasi-harmonic signal. We obtain analytical expressions for variance estimates and their displacement, confirmed by numerical simulations. Experimental verification of the method on a real signal confirmed the ability to determine its frequency with a relative error less than 10–5 in a time interval of about 30 periods of the test signal.
