"Measuring the phase shifts of quasi-harmonic signals" Ignat'ev V.K., Nikitin A.V., Yushanov S.V. |
|
A high-precision digital method of measuring the phase shifts is proposed for the signals whose parameters vary slowly over the time period equal to the discretization period but are able to change significantly over the entire measurement interval. Keywords: slowly varying parameters, least-squares method, phase shift, Taylor series |
