METHOD TO DETERMINE PARAMETERS OF WIDEBAND SIGNAL Russian patent published in 2014 - IPC G01R23/00 

FIELD: measurement equipment.

SUBSTANCE: method to determine parameters of a wideband signal consists in the fact that the signal is transformed into a digital form with the help of ADC, quadrature components are received A(ω), B(ω) at the specified frequency, quadrature components are transformed into the amplitude U(ω) and the initial phase φ(ω) of the signal, they form the amplitude-frequency spectrum and the phase-frequency spectrum of the signal, then they assess frequency ω=ω₀ and amplitudes U₀ of the signal by the maximum of the amplitude-frequency spectrum, they assess the initial phase φ of the signal using the phase-frequency spectrum of the signal in the point ω=ω₀.

EFFECT: increased accuracy of assessment of parameters of wideband sinusoid signals.
