Va. Dvinskikh et Sv. Frolov, An estimate of the parameters of the components of digital amplitude-modulated oscillations with a limited observation interval, MEAS TECH R, 42(7), 1999, pp. 717-718
A method of estimating the parameters of periodic components based on all a
pproximation of the readouts by a first-order trigonometric polynomial is d
escribed, and the possibility of a separate calculation of the spectra of t
he carrier and modulating oscillations is considered.
